yep... anyone laughing yet? I have a dipole hung in a tree... although its only 25 deet off the ground and needs to be higher... however the post stamp yard I...
Hello to the group, Anyone here ever purchased parts from Traffie? I purchased a used 5 band Hex and some of the parts are either cracked or missing. Thanks ...
Sure have, after a hurricane induced spreader crack; he and his crew had the new part in my hands in a few days after I called; great service from them. 73...
Correct me if I'm wrong but the internet Hex-beam photos and drawings I've seen all have the antenna spreading upwards from the vertical support structure Is...
I suspect the lack of gravity forces would make it more dependent on the spring of the spreaders to hold shape. 73 jim ab3cv [Non-text portions of this...
Henry: It should work fine electrically. But the biggest problem is mechanical. You would have to have a structural arrangement to replace the base plate or...
Hello all, a metal pipe is typically used for hexbeam support. If this mast were 54" long, and the feed line was ran up the inside of pipe, thru the...
Ken, I can't quite visualise what you are proposing. In principle it sounds like it could work provided the open end of the metal pipe is very close to the 6m...
It might be a problem modifying supporting the base plate in commercial units - but this could be overcome. It should be no problem in a Home Brew unit. Can't...
Thank you for the response Steve, When the CM choke is mounted below the baseplate, with feed coax connecting to the feed harness at the top, isn't that...
... Yes, which is why the feedpoint is a better position. By placing it another 54" below the baseplate the choke will be about a 1/4 wave from the feedpoint...
Steve, from your website down toward bottom: "Adding a choke to the feedline does much to restore the symmetry, and is an easy and worthwhile step; there seems...
Just a wild guess here, after one too many 807s but with the spreaders extending upwardly, don't the forces exerted by the wires counteract the tendency of the...
Scott, You've got a good point in relation to spreader sagging but whether curving upwards or downwards, the tension created by the wire elements would...
Ken, You missed an important quote from the same section at the bottom of that page: "Finally, please note that these measurements were all taken in the 20m...
Steve, I read these tests where for 20 meter band only, BUT the this meager brain didn't fully understand the full effects of "common-mode paths will be...
Am I missing something here, is this April 1st., do you guys have a different sort of gravity in the south?? It seems to me that an inverted hex would put it...
Ken, The problem is that the CM impedance seen at the feedpoint will not be the CM impedance of the choke, unless the choke is located right at that point. If...
Yeah, well -- I don't see HF hanging GP radials that are either horizontal or more often at an angle below the horizon, to achieve a better coax match,...

... The thought appeals to me, as well, but as others have said, there are some issues. In the upside down ("conventional") version, gravity wants to lay the ...
NOW it's coming together Steve. I thank you so much for hanging in there with my slow understanding. I've only started to get more involved in trying to...
My solution to this was to just buy 20 #31 cores about an 1" (from memory) long and sleeve them along the coax jumper going from the baseplate to the right...
... Hey Steve, thanks for making the point above. I have long known to put the choke at the feedpoint and even knew several reasons why, but, for some reason,...
... I have. My interests lie in making the whole center mast above and below one continuous metal mast so I can mount additional antennas, like a 2m beam,...
I had the same experience with a 15' pole from Walmart. I ended up putting some stainless steel wire in the very ends, but it was still much too flimsy. Wonder...
Has anyone tried to use the Telescoping 13' Foot Poles - Fiberglass poles listed on eBay to build a hex-beam. My main concern is will these poles flex enought...
