My tower, although modest, is very visible in the desert landscape. It was here before my last three neighbors built on adjacent parcels. They are all from California. They are all nuts. On 10/15/
A 21' length of 4" water pipe will do it without any guys if you can give up a couple of feet in the ground. I have a piece laying outside free for the taking. Wes N7WS I'm looking for a low-cost 2
Maybe he means on the inside:-) Wes N7WS RG-213 melts? Please explain. I have been using Belden 8267 RG-213 both on the tower (in hot climates) and in the shack for decades and I have not seen anyth
Exactly. http://www.radiomanual.info/schemi/ACC_rotator/CDE_HAM-4_user_W0MTU.pdf Page 6. I've had a "new" (never used) HAM IV and controller I bought on eBay a decade ago. Recently put up a short tow
That doesn't work. No matter how you choke the analyzer connection to the computer, it is still an unbalanced load. And you must consider it as a load, particularly if you're using an open/short lo
If the antenna needs a choke*, put it at the antenna. *Some don't, for example a gamma matched antenna, which is unlikely on a triband Yagi. Wes N7WS On 2/12/2021 5:23 PM, Dick NY1E wrote: A couple q
You should probably be using parallel RLC loads in parallel with the source. R + jX loads are not frequency sensitive, you get the same R and X at every frequency. In the EZNEC Help file see "The RL
On 160 CW about 30 dB, 20 meter phone, not so much. Wes N7WS if VE is worth 10-20 dB, what is P5 worth? _______________________________________________ ______________________________________________

My installation is MUCH simpler that those being discussed. I haven't implemented it, but I would consider a battery with a small solar panel for charging at the tower. Wes N7WS Right now, I'm work
Compared to dirt how important do you suppose that surface resistance is? Wes N7WS On 4/9/2021 1:06 PM, Dennis W0JX via TowerTalk wrote: I have a similar question. I have pulled copper 1/2" and 3/4"
Which version? I was following that group for a long time and it changed by the day it seemed. Did it ever mature? Wes N7WS _______________________________________________ ________________________
At least the plugs are good for 100k miles thanks to emissions requirements. Presumably, you'd combine it with something like a timing belt replacement. Regrettably, not true. My 2018 VW GTI specifi

You can measure the load with an ohmmeter. If it's open or measures too high, check the four screws that center the bottom of the load resistor in the shield for tightness. Wes N7WS John Owens - N7
