Dear fellow HB owners: I wish to report a serious infringement of the HB Owner's Code of Behavior. This sad event occurred yesterday, but I was too upset to...
Hello, I am trying to homebrew a Hex Beam for my attic. I am looking for exact measurements an an owners manual for a commercial one if possible. Does anyone...
Joe, My HX-5Bi is at 30' on a small tower. K6HJM has his Hex a little lower and near his roof. Given this, I would say that the Hex advantage at heights lower...
In light of this weekend's DX contest, I suggest that today's net be convened on 24956 at the usual 2230 CUT time to minimize QRM for all concerned. If no one...
I am trying to understand the tip spacing as shown in the article by Traffie. What do the two different tip-spacing measurements on the right side mean? What...
Joe, Don't worry about the overall tip spacing, the other is simply the length of string you will need to connect the end of the element to centre supporting...
Hi All, I've just put up a 40M vertical (Homebrew of course), and have compared performance with the Hex-Beam!! As would be expected the vertical pretty much...
Hi David, Interesting data point. Nevertheless, your earlier observations on out-of-band operation of the HB (using it on 40 and 30 m) did prompt several of...
All of the literature that I have read says that in a 2 elements yagi beam installation, the director gives better forward gain over a reflector. Has anyone...
Hi Joe, Well, that is what some folks think. The answer depends upon what your design requirements are to a large degree. Forward gain is only one parameter...
Hi Joe, You might enjoy reading LB Cebik's analysis of 2-element Yagis at http://www.cebik.com/beam.html. He ignoes the driven - director combination and...
Hi Barry, Yep, would agree, anything is better than nothing. I suppose one of the reasons I didn't work so much DX on 40 was that there are probably a lot less...
I need some clarification about the drawing in Traffie's article. The tip spacing is confusing to me. First of all, in actual construction, do the tips of the...
Joe---let me take a try at your question. If you think about the angle of the wires (or in some cases insulating line) as they leave the spreaders you'll see...
OK I didn't work him on the Hex, but just got P5/YT1AD on 40CW (50Watts). I think this will be a good one to test the Hex's performance against, thankfully P5...
Has anyone used PVC for their spreaders on the homebrewed Hex beams? I see that fiberglass is probably the material of choice but curious if PVC will work okay...
Congratulations David. I also worked the same P5 on 20 m CW about 2252Z. Seems that most folks believe he is a pirate. Many of us noted that his heading was...
Hi Barry, Well also worked him on 20M at 19.09UTC this morning on CW. Not sure if he was a pirate either but I was beaming North which is pretty OK for that...
Hi David, Just received an update from Daily DX by W3UR. It goes into some detail that this guy is a pirate. My beam heading was indicating Europe was the...
A 40m vertical will have low angle radiation, whereas a horizontal dipole for 40 at 1/4 wave height will have only high angle radiation. Since 40m can have...
I know that fiberglass is probably the most popular material for the spreaders. Has anyone had success using PVC? Also, how easy would it be to add the 4 other...
Joe, You need lengths round about the 11foot mark, so reason PVC wouldn't work. However, it was has to be a reasonably large diameter tube to stop it flopping...
Folks I have read the articles, the Web site and all you comments in this group. Let me introduce my self and my position. I have just about to get my licence...
... Depends on how big the roof is. If the roof is small compared to the wavelength, any height will be fine. If the roof is very large, then you need to get...
Cheers Barry, I suppose I should check whether my 40M QSO is Fair Dinkum, I was maybe a bit premature in my original boast. Regards David ... From: w4wb To:...
Hi George, Let me first answer that this is an independent Hex-Beam user group that has no connection with Traffie Technology. In fact, Traffie doesn't use...
George, Welcome to Amateur Radio! First off, I do not own a Hex Beam yet, but I am strongly considering one. I want to mention something about the 6m/2m/70cm...
When it comes to vhf simple vertical antennas, none beats the mechanical durability of the copper water pipe J pole. They last and last and.......... I gave...
Ok points taken on board. Unfortunately the Landlord is an organisation so it would end up as several nights out on the beer to succeed this way :) but it...
