I have the 3 el 40M3L and I find the curve is about as advertised at 90ft. 1.5:1 7000 - 1.2:1 7100 - 1.5:1 7150 - 2.0:1 - 7200. Ed N1UR _______________________________________________ _______________
I have never found an independent Yaesu rotor repair spot. Yaesu itself will repair (at least they used to) although it doesn't take long before you are buying a new unit. But you can buy the rotor u
It sounds like it's the radios or grounding. I run 20 and 15 with 2 of my monobanders that are 7 ft from each other. 1.5kW. No stubs. Dunestar filters at the radios before the amps. Excellent groundi
I am not sure that it matters but you should be aware that f the city zoning code actually says "amateur towers are limited to 40ft" then it is an unenforceable statute since it is preempted by Feder
Mark. That's A LOT of rotor for Rohn 25. I have 2 of them on my Rohn 45 towers. How much antenna are you turning needing a G-2800? Ed N1UR _______________________________________________ ____________
This happens to me about every other year. Usually right before CQ WW SSB as the weather gets colder through October (here in Vermont the night time lows are into the mid 20s by then). Its always a b
I have had 5 hits on or near the station in the past 15 years here. One hit my 80ft tower at the 15ft level - blowing a 10M beam up. Missing the rest of it above. Go figure. One hit the top of my 70f
Ditto..run, don't walk, from the F Connectors. Don't even think about transmitting through them. F Connectors are really fine for receiving antennas like loops or beverages, but it would give me the
There is no Federal Uniform Construction Code. Many States have a Uniform Construction Code that varies from State to State and many States do not have one specifically instead they regulate in other
Bob, I have a similar situation here. I just run the beverage wire approximately following the ground contour - however steep and undulating - about 6 - 8 ft off of the ground. My ground is thin tops
Yes Bob. Mine are tree and limb catchers as well and twice a year beverage walks are required to keep them whole. I have a total of 8 beverages that range from 600 - 900 ft. 7 are terminated - 2 are
Actually. The K9AY with preamp is a compromise antenna which is a wonderful solution where a full sized beverage or receiving array cannot be installed. But it is not comparable in performance with a
Why doesn't someone set up a survey monkey and lets see what is thought of by a large user group, not just a few posters. Personally, I am wit Tim, I don't find it broken. Ed N1UR ___________________
Don't confuse an uninterest in upgrading to the next thing just because it exists as resistance to change. Do you know how much money Apple makes on "the new iphone" that isn't much different sometim
All those who are needing to "upgrade" TT are free to move to the one that already exists on groups.io. No reason to get animated and bash the group here. Different opinions can coexist. There is no
A few years ago I started hearing a station on 80 and 160 using my beverage antenna. I thought it was a case of needing a BPF but as I experimented I noticed that I could not hear it on my transmit a
HFTA kinda sorta calculates stacking properly. It seems to assume you get the optimum 2.7db stacking gain whether the spacing is optimum or not. And it draws the HFTA ray from the center point betwee
I can't speak to NY State as I have not done a tower there. But typically, these guys are referring to Commercial tower requirements and not "accessory structures" not used for commercial use - ham t
I find it way easier and much more straightforward to simply record the specific X and R at the feedpoint when you install the antenna. Then make it a habit of check that measurement once a year at t
I believe that the reason it laid down full length is because it had a pier pin and the pin sheared when a guy let go. If the base had been cemented in (all 3 legs) like the majority of ham towers, i
