I want to have a 100ft 45G installed on my new property. It will hold JK Mid Tri 40 on top. I plan on adding a Yagi with a swinging gate at lower level later, and perhaps shunt loading for 160 and 80

I am getting JK Mid Tri 40 next month so this discussion is interesting. Regarding F/B, one question is how to measure it across the band to see whether reality reflect simulation. I erected Spiderbe

The difference on signal strength between a large pipe as and 18 ga wire is likely a fraction of a db. So the design of the pole is for stability and ease of erection not performance. The performance

I use crimping for a few months. It revolutionized my attitude to cables. When I need a cable of random length, I just cut the desired cable length from a spool and make connectors on site. For lmr24

The goal is to have 4 square for 80m with vertical dipoles a la K8UR, without compromising the performance of 160m shunt feed on the same tower. My tower is 100ft. If vertical dipoles have baluns at

Vertical performance greatly depends on soil conductivity and terrain. By reading many articles without good background you will be greatly confused. Whatever you do, I suggest you try to put a tempo

I shunt fed my 100 ft tower on 160 and I am thinking of 4 sq for 80m. What geometry of radials would make both 80m and 160m efficient? Normally, shunt fed 160 would need many radials around the tower

A tower is shunt fed for 160m and will be used to support 4 sq for 80m. A question is whether the radials systems for 160m and 80m should be strongly connected, weakly connected or disconnected. AC0C

It may be worth to point to a commercial solution: RX8-2 from Green Heron Engineering. 8 inputs to 2 inputs, with wireless switching and 12V supplied by DC injector. So just 2 RG6 cables to the unit.
