Here's the problem: A Hy-Gain TH3-Mk4 tribander works fine at 100 watts... but with a KW the SWR goes up when used for an hour or so at 50% duty cycle. I pulled the traps and all looked well except f
I hope the new Icom rig uses crystal filtering as well as DSP filtering. I have not found a single DSP Only radio at any price that could contest better than an old crystal filter rig worth $500 to $
When buying a used antenna or considering when it may be at the "end of it's life" one might want to consider where the antenna was located. I am finding coastal Florida to be much worse at weatherin
Hopefully Force 12 will use heavier gauge aluminum on their elements and booms one day. As-is the standard Force 12 antenna is built for light duty service. A fellow radio amateur here in Maine bough
If the SteppIR driven element motor does it's job and adjusts the driven element length properly... but either the director or reflector motor quits and does not adjust it's length accordingly for th
Hi Guys & thanks Steve for Towertalk We'd appreciate your thoughts. Our new club station site is limited to a tower height of 70'. We have two tower options we are considering. Please advise which of
Force 12 needs to do more homework. It should not be necessary for the consumer to have to do all this work (take the antenna down and modify it several times) to make a mass produced factory built F
QuestionWill Force 12 do refunds? I would have returned one if I'd known they'd take it back. Richard- K9OM << I would expect this degree of fiddling with a homebrew antenna, not something "engineere
A lot higher than 4-6 wavelengths. I ran a 10m yagi in EZNEC at 200 feet QUESTION: YES- EZNEC GIVES US A GENERAL IDEA... BETTER THAN NOTHING. BUT HOW ACCURATE IS IT? BUT WHEN EZNEC WAS CREATED JUST H
That's one of the great advantages of the Hy-Gain TH-6 and TH-7. They stay together when monobanders and flimsy antennas often fall apart. 73, RichardNO4S << They sure do! My first yagi was a home ma
I recently installed a 6-meter yagi with a 12' boom... 6-1/2 feet above a 5-element 10-meter yagi with a 24' boom. The 10-meter yagi continued to work great but the performance of the 6-meter yagi wa
Hello TT- I am a registered user of TA. Does anyone have ".PF" antenna files for antennas other than those originally included with TA... that you would share? (possibly e-mail to me). I am especiall
Hi Natan, I recently had a very poor experience with Force. First, I had an installation question and called and fax'ed Force... but I never received a reply. Second, the C-19XR is a very flimsy buil
I would like to improve the gain on a A505S Crushcraft 6-meter yagi. I would like to keep the 12' boom and change the element spacing if it will improve the forward gain. Would eliminating one 1 elem
Please advise the best spacing to use between a Tribander and a 6-meter beam. The tribander is a Force C-19XR and the 6-meter yagi is a Cushcraft A50-5S. Would 7' be a good spacing? Thanks! Richard-
Towertalkians, I believe in using EZNEC (and similar programs) to model antennas in order to get a guestimate as to how the antenna will work. But I question the accuracy of such programs. Such as: c
I would be grateful for any information about the Weathertronics 8511 (HG55SS) crank-up tower: Manufacturer, antenna load, foundation needed, are they a reliable tower for ham use? Thanks- K9OM -- FA
Towertalkians Thought you should know about a rediculous problem occuring with Hustler antennas. I purchased a new 4-BTV vertical this Fall. The 10-40 meter vertical would only work on 10 & 15 meters
