My new article about operating Ham radio at castles in Japan has been published in the March 1st edition of FB News. This month's article is about planning and preparing for a visit to a castle, and it features the Buddipole system as my main antenna system. Please check it out, if you will.

Don’t give up so easily.  You have all the things needed to experiment with.  Night time on a deck if you have one.  Attic?  Or living room by the picture window.  And what an antenna out of your trunk running portable.  You will be blown away by what you can hear when you get away from all the noise in a condo/HOA. 

I have seen them on a screened in porch decorated with artificial flowers or vines and work well.  

Yes, this is a good deal for someone else if you must sell it.  Mine travels with me to our condo in Florida every winter.

You will see I bought it between September and October 2020. Deployed it three times exactly in my backyard, and it was never under the rain. It is basically new. The package includes:

First Invoice, dated September 18th 2020 (total I paid $701.03):

- Antena Deluxe "Long package" with 2 knurled whip sleeves
  This package features our long mast which extends to 18' in height (19' when mounted in tripod). The additional height is ideal for operators who are looking to increase antenna height above ground to improve efficiency and lower the takeoff angle of the standard dipole configuration.

Our long package has a few other differences which set it apart from our regular Deluxe Package:

New Choke Balun
50' Premium MILSPEC Coaxial Cable (RG58/u), w/SO239 adapter
Included guying kit
Padded Cordura carrying bag (40" in length)
Otherwise the antenna and other extras that come with our regular Deluxe Package are the same as with this long version.

- Triple ratio Switch balun TRSB
- Vertical antenna clamp with mounting kit 
- Wire Assembly 

Second Invoice, dated October 19th 2020 (total I paid $146.24). This is perfect for Vertical deployments):
- Mini Banana plug leads, 6 inches
- Mini Banana plug leads, 9 inches
- Counterpoise wire adapter
- Wire Assembly (2 more, so there is a total of 4)
- Four (4) antenna arms 22 inches.

Please see the invoices and go to the Buddipole website for details of everything. If you or anyone you know is interested, please communicate “only" directly with me (please don’t reply here) at: omanero@..., and include your name and sign.

Spend $75 on a Sark100 or something similar. I have a Sark and a cheap android tablet that I have used to tune the counterpoise on a vertical Buddipole. No radio is required. The software is a little buggy but $75 is hard to beat for what you get.
I started off with a 1/4 wave vertical, rolled out 1/4 wave of counterpoise connected up the Sark100 and ran a graph sitting about 20ft away - the Bluetooth connection to the tablet allows this. Keep the counterpoise +- 5’ off the ground or more. Then either wind back the counterpoise wire back onto the handle or wind it off according to what you see on the tablet. This will shift the frequency of the troughs. I ended up with a vertical that had me easily contacting all of South America and the Caribbean, Europe, Russia and even New Zealand with 100w about 4 years ago with almost no sunspot activity at the time. I guess you could look at trying to adjust the vertical length to keep it synchronized with the counterpoise length, as technically you would have an OCF antenna if they weren’t perfectly matched, but I didn’t bother and it worked really well. In my case I actually used a vertical that wasn’t quite 1/4 long and added a base coil which I adjusted based on looking at the Buddipole tables and seeing how many turns of the coil shortened the length of the slide/telescoping part of the antenna. Using the coil probably influenced the Q of the antenna and made the troughs sharper, but the Sark lets you put the trough exactly where you need it for the part of the bandwidth you are using. I also used an antenna tuner to tune out any final imperfections and it usually tuned these out within a second or two of pushing the tune button.
Here is a Sark display for a ZA6BKW antenna I am currently using to give you an idea of what they look like (cropped from a photo of the tablet screen). You can, of course, change the center frequency and frequency step values to zoom in to any portion of interest). Really easy to do once you have set it up. I did find changing these values a bit buggy - had to put a leading space in and make sure that the frequency range shown on the bottom of the screen actually changed...

Re: Tuning the Buddipole

Tuning a Buddipole without an antenna analyzer is cut and try and wastes a lot of time. I have one and an analyzer tells me where I am in frequency, impedence and SWR. Write down you results as a starting point the next time you use the antenna. The results will change with each different location.

My favorite analyzer is the YouKits FG-01 as it only showsfrequency, SWR and impedance. Turn the knob to vary frequency and watch the parameters change. No fancy Smith charts or other stuff I need to interpret. I have more complex analyzers I have bought since I got the FG-01 but they sit on the shelf unused out in the field.

Using noise and your xcvrs SWR bridge works but just takes more time.

The other side of the coin is what we did when Novices back in the 1960’s. Just hook up a wire and transmit. I always made contacts even with lousy antennas (by today’s standards). Some of us get too hung up on having everything perfect and get discouraged too easily. Ignorance can be bliss. Just tune for maximum noise and watch the SWR that it isn’t too high and play radio. There are a few sun spots these days and they are a hams friend. The more the merrier.

The old ’noise’ method (drag clip down the coil) doesn’t work with the shock cord whips. I suppose I can start by using a calculated length and then tweak up or down to get the right SWR (I generally use an analyzer). But there are two variables, the whip length and the counterpoise length. Is there a formula for each? When tweaking the antenna how do I know when to adjust each? I’ve looked at the files as well, but they don’t list all the variations of shock cord whips, and the ones I have are not listed in any I’ve seen.

I don't have the answer but a related question. I guess you are talking about a vertical BP. I don't understand why you say: "The old ’noise’ method (drag clip down the coil) doesn’t work with the shock cord whips". Why doesn't it work? Aren't you referring to moving the taps along the coil? Or are you refering to shortening the telescoping stainless whip. Obviously the military whips don't telescope.
I am using telescoping shock cord whips. I’m understanding that on some bands I don’t need a coil (hence the reason why the noise method doesn’t work). I suppose that theoretically you could adjust the whip length while listening, but (a) your hands on the radiating element probably will have a significant effect on the results and (b) I often have the radio too far away to hear. I want to be able to do this with an antenna analyzer. I own two of the RigExpert analyzers. It can make nice graphs of a range of frequencies (like one or more bands). It also has an SWR meter mode that will continually show the SWR as adjustments are made. I suppose I would use that instead of using the radio noise, but I’m still concerned that my touching it will have a big effect. Since I’m not getting much good advice I guess I’ll just experiment. I was hoping to benefit from someone elses experience.

Now to my own question. I use the military whips (4-section) with the longer coils. I am having trouble getting my dipole resonant where I want. My NanoVNA is telling me a different story than the BP table for the military whips. What I want to do is minimize the need to change the taps for every band change, which is very inconvenient. I learned(?) once that a 40m dipole was also resonant on 15m and 6m, and those three bands would suit me fine. But does that stand (if even true) with a BP coiled dipole tapped for 40m? I should mention that my BP installation is permanent, not portable. It is across my 17" balcony - the exact length of the BP setup. It is suspended from the balcony ceiling, about 10' up and so hard to access to change the taps.
Is the difference significant? Remember that the BP table was written for the BP mounted in free air mounted 8'-16’ off the ground on one of the Buddipole masts. Your mounting on the balcony likely means it is proximity to building materials which probably are changing the performance a bit.

I’m not sure about the 40m/15m/6m question. I’d heard about 40m/15m, but not sure if the Q of the coil will impact the performance across multiple bands. Good luck.

One counterpoise yields a null to the non-counterpoise side.

I like to run two (180 degs apart) and also adds some stability to the elevated setup as a bonus.

I am not sure I agree that the null is as insignificant as you believe.  i have never measured it, but many have modeled it.
The 3 page in the link displays a pretty good size null.   Either will work, I am more concerned about the null is my receive.
Wife says an antenna wont help my lack of listening skills :)


I see that steppir ad indicates that 2 tuned raised radials are equivalent of 120 ground radials, and that is approaching 90% efficiency.

I agree with Bob Lewis, I’ve found a single radial to work just fine in all directions. A “null” or dip in dB is really quite small, and when you consider that 3 dB is half of an S number, neither your radio or you will care much. It’s kind of like the specs on receivers. What generally governs is band noise which requires good noise reduction techniques, not a more sensitive receiver. I’ve learned to never let physics get in the way of what works ;-)

Re: Tuning the Buddipole

Bob
 

I agree with Bob Lewis, I’ve found a single radial to work just fine in all directions. A “null” or dip in dB is really quite small, and when you consider that 3 dB is half of an S number, neither your radio or you will care much. It’s kind of like the specs on receivers. What generally governs is band noise which requires good noise reduction techniques, not a more sensitive receiver. I’ve learned to never let physics get in the way of what works ;-)

Good discussion,

Spend $75 on a Sark100 or something similar. I have a Sark and a cheap android tablet that I have used to tune the counterpoise on a vertical Buddipole. No radio is required. The software is a little buggy but $75 is hard to beat for what you get.
I started off with a 1/4 wave vertical, rolled out 1/4 wave of counterpoise connected up the Sark100 and ran a graph sitting about 20ft away - the Bluetooth connection to the tablet allows this. Keep the counterpoise +- 5’ off the ground or more. Then either wind back the counterpoise wire back onto the handle or wind it off according to what you see on the tablet. This will shift the frequency of the troughs. I ended up with a vertical that had me easily contacting all of South America and the Caribbean, Europe, Russia and even New Zealand with 100w about 4 years ago with almost no sunspot activity at the time. I guess you could look at trying to adjust the vertical length to keep it synchronized with the counterpoise length, as technically you would have an OCF antenna if they weren’t perfectly matched, but I didn’t bother and it worked really well. In my case I actually used a vertical that wasn’t quite 1/4 long and added a base coil which I adjusted based on looking at the Buddipole tables and seeing how many turns of the coil shortened the length of the slide/telescoping part of the antenna.
