Hi, I have added some pics. of my hexbeam under OZ6ABM - 5P5R. Some details: - the beam is mounted on a telescopic antenna mast. Retracted at about 8 feet high...
Robin: Congratulations on the new hexbeam. You used your imagination to come up with some unique ideas. Keep us informed on how it is doing. Leo, K4KIO...
Hi Steve, The beam is performing OK. Just being able to use 5 bands instead of 3 on the old tri-bander makes a big difference when going to 12 and 17. As you...
I have noticed some disconnects between what I have tested and other anecdotal construction details on RFI prevention and choke design. I offer these...
If you plan to try fiberglass electric fence standards for arms, then don't use the 10mm, they are too flexable. the shape they form with 2meters of 21x1mm...
Very nice discussion Chuck. I have helped many people solve their shack RFI problems using RF chokes. I would like to mention a couple of things. Type 31 is...
Ian, Are you talking about 2 meters for each arm? I've no practical, nor modelling, data to go on but my instincts say that is a lot of metal to have so close...
... two do you use and why? ... Thanks Wendell. Frankly Wendell I would use all type 31 if I had sufficient supply of it. I simply had a lot of type 43 here...
Type 31 is an ... Hello Barry. I didn't have any type 77 or 73 so I cannot comment on it. I did have and measure 43 and 31. Also would refer you to the ...
Hi Steve Thanks for the reply, I hardly understood my own message when I reread it, should not have pressed the send button so quickly. I used 2, 2 meter poles...
Hi Chuck, Interesting paper you referenced in the files. I note that he counts his line passings a bit odd. The upper has 3 passings and the bottom two. Net...
Hi folks, Like many keen folks on the list i am planning a Hexbeam for the shack. I can get a roll of 1.6mm hard-drawn copper wire at around 58M in length, and...
Hi Chris Another alternative is to use Dowel. It has to be well sealed to survive the weather. Also Tasmanian oak seems to be the best and is available up to...
Hi Stuart, I've heard of the PVC/Dowel combo before. Dowel seems a bit stiff to me, does it handle the bowing required in the "upside down umbrella"? Perhaps...

Let me offer several data points. My actual measured (common mode) results with Type 43 material is 3400 ohms at 14 mhz. Have you measured type 77? I simply...
Chris, Remember that the 17m thru 10m wires don't take any strain, and nor would the 20m wires if you were to leave in place the 12 cords used to pull the...
Ray, A few thoughts: 1) Bad News: if you move to separate feedlines, but stick with the "multiband" wire dimensions you may find that the SWR is marginally ...
To followup on my recent posting asking about telescoping mast choices - I've purchased a 40' Rohn/Radian mast. I found it at Ness Electronics in St Paul, MN...

Had much the same issue myself regarding the top mounting. I cut the bell part off the center pipe. The straight pvc end goes into the top connector of a tv...
I have almost the same set up. Mine is about 3 feet below, with no interaction. Second set is about 4-10 feet lower...and the base is bracketed to my qth. Good...
Rick Yes... originally my plan was to put the rotator at the top of the mast, however when I tried raising the mast without the rotator and antenna it was...

I have my hexbeam on a Rohn 50ft telescoping mast extended to approx 36 ft. The Rotator is mounted at the bottom and I use 3/16 dia phillystran for the Guys. ...
