I have 2 - Yaesu 2800s. They have never failed for loading. I had one go south after a direct lightning hit. One has 6 el 15M 44 ft yagi and a 4 el 20M yagi on a 36 ft boom. The other has a 3 el 40M
I have seen these depictions of the guy wires so low on the tower however I have never built or seen one done that way. Typically the top guys are somewhere on the last section. Personally - I like t
Hans, An 85 ft tower with only a guy at the top doesn't sound safe to me. If its intended to be guy'd, unless its something like Rohn 65, that can't be a good design. And even if it were Rohn 65, I w
I am surprised that no one mentioned the heights or spacing of the yagis. Even for the Pacific NW, the lowest yagi of the stack being at 90 ft seems way too high. Especially if there is any terrain e
The question was actually not about feedline. However - what feedline is part of the dialog I think. And whats the cost of feedline vs the more complicated triplexer/pentplexer solution. 500ft is a l
I have 2 towers separated by 140 ft. Monobanders. The towers are running roughly N/S so I am not fully pointing at one when beaming EU but its not "tip to tip" either. I run FT1000MPs with ACOM and A
To be clear, my set up is not having a problem. I have noise floor capability on 10 - 20 and a little noise on 40/20 but still less than S1. 80 and 160 are somewhat more problematic but not affecting
Actually - Copper is at an almost 2 year low right now and about 30% less than its peak in 2012. Ed N1UR _______________________________________________ ______________________________________________
I am sure that many of you have heard about a recent tower climbing death installing 70ft of Rohn 25G. The details of the story made me think about my tower building processes and I am wondering how
Herb, KV4FZ "I would have been more active but forgot about the contest. but many do not know that KV4FZ is an original VI call sign and still is located on St. Croix. BTW.....NP2P is a club call fro
My thoughts would be the following on this: Bringing the feed point about 20 - 25 ft away from the tower and letting it slope up to the high point would help to de-couple. Obviously the radial system
"Isn't that pretty much what I inferred?? You put it up as high as your location and checkbook can stand and wait for the propagation gods to smile on you." Wes? N7WS Actually Wes, this is 100% wrong
Those that are firm believers in modeling should understand the purpose and limitations of their modeling software. "Antenna Modeling software" is used to design an antenna above a modeled ground pla
I am curious why you would want this. I had the 4 el version for years - 34 ft boom I believe. It's a beast, the matching system is not the best, and the element spacing is not ideal. You can't chang
I use the M2 3 el beam on 40M. I have it centered on 7080 and that gives me a 2:1 SWR BW from 7000 - 7200. It rises steeply from 7150 so by the time you are at 7275 the SWR is at 3:1. But inside the
I have had this problem as well. Its usually a bad braid to connector - through oxidation or temp cycling over time. Hanging on by a thread and the RF affects the connection. Never shows bad on trans
Rich, I am glad you found the problem, but my guess is that you only temporarily fixed it. My experience is that this stuff re-emerges, usually after temp cycling a bit, sometime a number of months l
I don't think I took part in the survey but the Yaesu G2800 is a fabulous rotor period and for the price there really is no comparison. Skip the control box and buy one of the other control options t
Clearly the foundation is everything when putting up a self supporting tower. Limestone is very possibly digable for this purpose with right machine. You should talk to a backhoe guy that has a good
Wow, seriously? Like cut 1, then 2, then 3? Did they loosen them on the ground first so they were essentially "flapping"? I have to hope so. And how far above the next set of guys was he up there on
