Hi I think your solution is financial, not mechanical. Sign up customers needing towers with a fixed-term contract into which you incorporate the cost of the tower into the monthly rate. Here, some w
I've read Jim's choke cookbook, and I won't pretend to say I understand all (maybe even any) of the math involved. However, I can't escape the feeling you both reading too much into his design of an
I will admit I was suckered into the idea of using a connector on my Ham-x style rotator. I've changed the rotator, let's see, want to make sure I don't lose count here, ummmmmm, ZERO times in almost
DX Engineering is selling Powerpoles for $12.95 for a pack of 20. Price is hardly a deal-breaker. 73, kellyve4xt _______________________________________________ ______________________________________
A few suggestions, in no particular order: Use the 140-foot pole as the top support of a bent, tilted 5/8-wave vertical (about 150 feet will have to come down the other side (following what would oth
Which isn't necessarily a bad thing, if you go in with your eyes open. The F12 C3 was the same (2 on 20, 2 on 15, 2 on 10), although it appears the driven on 10 was doubled, likely for bandwidth purp
Hi Roger, Do you need penetration? Or would sealing any exposed strands (such as the end of a wire poking out from a crimp) suffice? Such as: crimp wire to connector, use flooded heat shrink to shrou
The TX-38 was sold to DX Engineering and was subsequently discontinued. It was expensive for only having three bands (it was almost Bencher Skyhawk money), but it did look like a fabulous design, par
Insulation is a good start, but air movement is the enemy, too. Chris's dual-plate idea is a good start, but an easy way to satisfy both the air seal and insulation requirements would be to create it
There are lots of good antennas that have left the market over the years. I suspect a lot has to do with the fact the market in ham radio for anything that doesn't have a belt clip isn't huge. Also,
JK has a tribander like the TX 38 (4 on 10, 2 on 20/15) for less than a kilobuck. If you, like me, couldn't give a rat's ptooey about 12 and 17, this looks like a good option. If you don't need the a
Not that baluns or chokes are a requirement in every situation, but "back in the days" they also thought connecting one side of the A/C to chassis was a good idea, too. At least today's Pin 1 problem
It's the classic marketing axiom: tell people what they WANT to hear, not what they need to hear and, often, certainly not the truth! A lot of marketing, even in a relatively technical field such as
Can I step back and ask a bigger-picture question? Given the short distance between top and bottom antennas, is there a benefit to this kind of array vs. interlaced monobanders on a common boom? In F
The roof mounting plate, as described, seems to solve a few issues relative to embedding tower sections or base tubes in concrete ? helps prevent water intrusion into the base, permits re-use of base
It's hard to tell from the Hy-Gain owner's manual or parts list, but... Are they really selling aluminum base tubes to embed in concrete? I'll take the OP at his word, but given what we know about al
Aside from an intellectual curiosity, which amateurs ? aside perhaps from EME or terrestrial VHF/UHF enthusiasts ? need to know north any more accurately than something such as an iPhone provides? It
Tom says he's bypassed the tuner's meter and the creep upward is still apparent. From his description, it appears he's narrowed it down to six components: the two variable caps, the roller inductor*
I was once at a Field Day where a ham then with more experience than I claimed our dipole wasn't working because we hadn't put a bay-lun coil on it. 73, k ve4xt Sent from my iPhone __________________
Can anyone imagine what problems of the world we could solve if we put as much energy into something that actually matters? 73 Kelly ve4xt Sent from my iPhone ________________________________________
