All- I just raised my broadband hexbeam that I put together based on Leo's plans on my roof on a 10ft pole for a total height above ground of 35ft on one end...
Hi Robin, It's probably difficult to model this situation so here's a non-scientific experiment you could try. Take SWR readings on 20 meters at different beam...
Hello Robin and group; I have a dual band dipole strung just underneath my hex and it is only a few feet below the 10 meter elements. The dipole is for 20 and...
Robin, The most sensitive indication of interaction between the antennas is likely to be the *rearward* performance of the hexbeam; that's because you have...
Thanks for the suggestions. I just ran a test with and without the OCFD raised. Using the SWR test, I did notice any difference in SWR with or without the OCFD...
anyone on the reflector live in Odessa, tx???? found what looks like a dx eng hex up at about 45 feet here in Odessa, tx and wondered who they might be.......
I recently heard about hexbeam.What I would like to do is build a hexbeam for just 10 meters and if succesful go ahead with a multibeam.My problem at the...
Hi Ed, Did you move to Odessa, TX? I will fly to Atlanta, GA on Wednesday, February 8 and will be there a few days for a business trip. Regards, Koichi JR1MLT,...
Hi, Â Â have a good trip..but yes I am here in Odessa for work so kinda moved here...will be commuting home as much as I can..LOL Â Â ED NX7TT Idaho Falls,...
Hi Matt, http://leoshoemaker.com/hexbeambyk4kio/general.html http://www.karinya.net/g3txq/hexbeam/broadband/ There are two types of hexbeam: 1)The "W" shaped...
Looks like many of you use the HD-73 to rotate your hex beams. I've been given information that the HD-73 is derated from 10sq ft wind load down to 5sq ft...
I have now built several of the 6 band Broadband Hex Beams using the information from Leo and Steve. A local ham friend of mine said he was interested in a...
The strong gusts of "Bora" at about 150 km/h in these days has broken some of my hexbeam wire, made ​​with bare copper wire of 1.5 mm in diameter,...
I'm in the process of setting up a K4KIO hex with that very same rotor, so I'll let you know. I'm going to mount the rotor at ground level with a Rohm...
Hi Steve, For now, the base material is Star Board. It is similar to the stuff cutting boards are made but is UV resistant and more $. I have used it on my...
While generally a mild winter, I again find myself with a fully ice coated Traffie 5 band hex. I noted previously that the SWR shot up. Same again but this...
Hi Steve, It's 3 hours later and the temp has risen to 36 degrees F and my SWR is back below 1.5:1 on all bands. This antenna does not like ice on the wires. ...
Mike, I have had my Traffie for 7 years....I always had issues with snow/ice...you are right to assume, it does do well . 73 John/k3jvb In a message dated...
Hi A friend of mine built and put me homebrew hex 6 {band 20-6m) its to replace my 3 ele tribander... Im Very impressed in its DX capabilities, Ive already...
Daz....I have a Traffie 10 thru 20meters hex. No issues with rain. But ice does have an impact on swr. But then again, I think ice will effect most beams as...
I know i have said this many times....but now after 8 years with my traffie beam I have had ice and snow and rain with no issues... Â have been lucky i guess ...
Ice has a dielectric constant of about 4 relative to air. Even a fairly thin coating on the elements of a yagi will lower it's resonant frequency and degrade ...
Thank you for the info Pat. And yes, every antenna has problems with ice, My sirio 2016 vertical, metal, 10 meter antenna has swr changes if there is ice on...
Anyone tried a hexbeam atop a 43ft vertical? That is a 43ft vertical used for transmit purposes for 160-30 while the hex serves the upper bands. I'm thinking...
Hello group, Consider the following picture: http://www.universal-radio.com/catalog/hamrot/4230.jpg The picture describes 3 different ways of installing...
