Interesting to hear comments on this. This question starts with how much weight is to be lifted and also what is going to try and pivot if you release the bottom of the mast from the rotor clamps. He
The C3 is the best short boom tribander out there in my opinion. I have used them around the world. They are a clean pattern, smooth SWR across the full band performer. At the end of the day, the gai
I believe that for that kind of change, the inverted L is hanging just different enough than the original that it is coupling differently to the tower or possibly the ground. Was it looser before, or
Relative to PRB-1, there is a very real issue here. What regs are they applying and why? If they are applying commercial tower requirements to your FCC protected amateur installation then yes, PRB-1
Always an interesting topic. I wanted to offer my opinions on this subject for consideration: The system has four purposes - 1) Static discharge to avoid a build up 2) an efficient leader to attract
You should really look at all the options to put whatever antenna you are trying to support if its truly only needed at 26 - 28ft. What are the regulations for "accessories to your already permitted
I can tell you one reason to spec RG213 over LMR400 to feed your Mosley tribander, or any other tribander for that matter. Your SWR will look better than it really is due the excessive loss of RG213
Hi I wonder if anyone has modeled a owa antenna using the existing element taper an diameters from? the Hygain series 105,155,205 antennas I have several of these I would like to make them into owa d
The 4el yagi is on top of the tower at 80 ft. The 8 el yagi is at 30ft fixed to EU. So yes, there is sometimes some angle optimization that would explain the larger than expected gain difference. But
As the reigning Low Power USA DX Contester(currently) in many of the popular DX contests, I think I can speak with some experience on this subject. One year - I think it was 2009 - I was sick and kne
Answers to questions below: Content-Type: text/plain; charset="iso-8859-1" power u have there, with say exactly 100w applied in the shack ? Answer, no but I did measure the cable losses by disconnect
It seems to me quite clear as to what Mosley's strategy is. "Make my HF amp happy and let me crack most pileups in a reasonable amount of time and I am a happy DXer". That means the lowest SWR at the
Don't be afraid to actual do your own survey for the first part. For 80M, the "near field" which usually defines 90% of the terrain effect unless you have a HUGE drop off past that or a HUGE hill blo
Its an interesting thread. A few comments. - Its all about gain. You don't care about F/B because if you can consider these antennas, you are going to have beverages. And if you have good beverages,
Sorry for the confusion - some clarifications below: There is a lot wrong in that post. 1. HFTA doesn't model vertically polarized antennas, so if the conclusion is to go with a 4-square you aren't g
I thought for sure that I had seen elevated radials and a groundscreen pictures from K3LR but clearly they are not. They are a 120 ground radial pattern. Sorry for my mistake on that. Ed N1UR I'm con
If you actually care about your loss on 10M, why are you using a 150 ft run of RG213? It should be at least LMR400 and preferably LMR600. Ed N1UR _______________________________________________ _____
I will add to K4XS comment on the 15M 6el M2. I am also fan of M2 antennas, The 15M 6el boom is spongy. So spongy that honestly the center of gravity is not really that material relative to some numb
Has your rotor been the same rotor for the 25 years? One possibility is that your tower has never been truly plumb and that there is a small amount of "weight lean" on the thrust bearing. Your strong
Snip I'm wondering if there have been any attempts at more than 4 element SteppIR's? I'm happy with my 4L but it would be nice to have some more smoke. What might be interesting are some longer boom
