You have to get HFTA. It's just that simple. You'll get a good picture of what your antennas need and it will help you avoid overkill, which helps avoid added costs. Too high an effective height can
Hi Pete, It seems to me: you're attempting to couple both your two-way HF energy and the UHF energy required for switching onto a common feedline, is that right? It seems it would be doable, but the
Hi Frank You might be thinking a bit too linearly. I have a feeling that modeling becomes MORE important the LESS you have to spend. Your 1/2 wave example might be the perfect launching point. It's a
Seems to me the question of where to tie the upper pull ropes depends on the position of the tower. If it's alongside the building, you should be good to tie it at the top and pull. If it's laid out
He didn't say it was a guyed Rohn. Could be BX or even SSV. 73,kelly ve4xt _______________________________________________ _______________________________________________ TowerTalk mailing list Tower
Hi, Anyone have any recommendations for boots for tower work? Iım thinking light weight for climbing, but sturdy of sole for standing on rungs... 73, kelly ve4xt -- Listen to THE ROAD TRIP on CJOB ev
Not sure it answers the problem entirely, but Dave, I noticed there is a bar that connects box to a second tower leg. That spreads out the load, but I'm not convinced that it's by enough. Curious as
I would think you might be asking for trouble: anywhere on the side and you're going to mess up the tuning and the pattern, and on top you might have structural issues. If top isn't out of the questi
The mechanical considerations of mounting a 43-foot vertical topside on a tower are considerable. But the electrical considerations aren't trivial, either. As I understand, without proper isolation o
Rick, YES! Thanks for reminding me. You're absolutely right. And now that you've reminded me, THAT is exactly the conclusion that K9YC came to. _______________________________________________ _______
One thing I considered but never tried was simply using a double-female UHF adapter, with the centre conductor of the hardline exposed so that when it fit into one end of the adapter the end of the a
Another repetition of the exploding base myth. If concrete is so explosive, and such a poor conductor, why is it often used to assist with rod-earth connections? As well, the very existence of the Uf
Hi It would make sense to confirm the A3 as the cause of interaction first, no? Thinking you could simply lower the A3s and then determine what effect it has on your VHF yagi. Also, how do you know t
Seems to me the more important consideration is whether 5x5x7 is enough for your specific situation. Most such plans are counting on a certain firmness to the soil, rather than relying solely upon th

Hi Jim I never tried elevating my HF6V (similar in principle to the 2V), but I'm not surprised by your results. My HF6V worked OK on the high bands, OK on 40 but was little better than a dummy load o
It would be a shame to not be able to use this dipole, since your vertical antenna won't come close to it without a lot of radials. I suspect the problem isn't the antenna but rather the feedline. I
Gee, I didn't realize that Ward and Steve's exhaustive tribander tests and subsequent report constituted 'no facts' to support Jim's argument. Seems to me the majority of knowledgeable antenna folks
As I recall, the US government also bought a bunch of those Maxrad dipole centre insulators that a band saw revealed to be nothing more than a non-reactive resistor between the dipole legs. 73, kelly
Yup. And I've broken through mondo pileups on DX stations first call with my MA5B at 30 feet. I've had folk in SS say I'm the loudest guy they hear. One guy in California said I was 40 over s9, and I
