just to add to my last, 15M is OK and I had a fault on the plug. SWR on 15/12/10 is about 2.5:1 at resonance, but that is with the antenna sitting on the roof...
... airtime (thus, actually much less), on 15 meters only, I logged 223 prefixes, 170,000 points and...73 DXCC entities!!!!! ... As I had to spend about 23...
Hi to all: Here are the results of a little test on the best tower height for the hexbeam. I talked to Mike Traffie last week on 15 meters and he asked me to ...
... Look at the math: St. Louis, MO: 38.63N/90.24W Ashby, MA: 42.67N/71.82W Distance = 1005 miles A 15 meter horizontal antenna at 1.7 wavelengths up will have...
Hi Brian: Thanks for doing the math. I think I need to get a motorized tower for my Hexbeam!!! Tom, N0YD "Yankee Doodle" ... towers. ... was ... single ... ...
Hello to all: I fully agree with Tom (N0YD)..."bigger isn't always better". My HB is about 30 feet above ground, with its base only about 6 feet above the ...
Yup! Given the realities of antennas and propagation, I think a motorized tower is probably as valuable as a rotator -- although much more expensive ;-) I'm...
As perhaps the least technically knowledgeable member of this Board (so I don't guarantee I'll understand the answer), I wonder if anyone has any thoughts on...
That is exactly my plan Tom. I will be refurbing an old 50' EZWAY tilt-over, crank-up tower this summer. While I have the welding stuff out to touch up...
If you have not voted in the poll, please do. You have to get to it by going to the group's Yahoo! web site. FWIW, your vote is secret from everyone...
Again, for those adventurous amongst you!! I have carried out an initial pruning of elements and have the antenna at about 15foot (4 foot above the metal shack...
While it might be advantages to have a small wind load like the Hex offers, consideration to wind loading is still important. The basic formula for wind load...

In addition to my previous posting on wind load. Remember, when rating a guy cable/rope/etc., always calculate the worse case situation, then look for rating...
Apologies as you are all probably getting a little bored with all this ''Homebrew Stuff''. I have just uploaded a graph of SWR plots for the MKII Homebrew Hex...

Hi David, not bored at all!!! My attempt will be one-line-fed system (just to have had the experiance...)sorry it take's a long time untill i'm there, but you...
Peter, Thanks for the mail, and sounds interesting. One other thing I would suggest is to make sure that you can adjust the points at which the elements...
Very interesting. Yep, the resonance does vary a fair amount from the low to operational height. Great progress. The F/B seems about right. Hope the gain is...
Hello to all: Once again, Barry The Elder (aka Uncle Barry, Barry The Wise) has done it! The following text is from his latest email (color added for...
Gee Herb, I think you made my point exceptionally well. :-) So have you mounted your Hex-Beam upside down yet? 73 de Barry - W4WB ... done it! The following...
Herb, I hate to get into this but maybe Barry has a point. Both coasts seem to have a pretty easy go of the DX. I have often heard stations calling for the...
Hello again to all. OK...I give up! I try to do my best to bring a civilized message of hope to those not living the California Lifestyle, and what do I get?...
And there's more! Well, F/B ratio seems good on all bands 20-12M (still no propagation on 10 to check), with between 2-4S units depending on location of DX...
Hello Dave and all, I am new to the group. I will like to try to homebrew an hexbeam for 10-15-20 mts. I have read your messages with a lot of interest and ...

Don't give up, Herb. This is just beginning to be fun. I called the Kansas City Chamber of Commerce to get some stuff about the midwest quality of life for...
I've uploaded some pictures sent from Joe, AA5HP, ("hope you don't mind Joe!!")showing his multi-band Hex centre post. They are in a folder in the pictures...
