- Don, Build a three or 4 wire cage around the tower from top to ground out 24 inches #10 or 12 bar copper is fine. A few standoff PVC or fiberglass will lessen changes in high wind conditions. Measure

- Reading about 3-wire cages and the like, I feel a serious case of shunt envy. Mine is a single wire about 18 inches from one corner of my Rohn 25, connected to the tower at about 50 feet. I used an o

- I place all rotor wires and other cable through a few 3" Ferrite rings at the base of the tower with as many turns as I can squeeze on. Before doing this I had a slight deflection in the rotor indica

- Which is the same height as the one I had in the 80's at another home. With stacked 10-15-20 W2PV-4's it resonated somewhere around 1530 KHz if I remember and an Omega was the only thing that worked

- All I had on my tower were the 3 coax cables and rotator wire which were all taped to the tower about every 5' which apparently decoupled them. The coax also had about 15" of large 43 mix ferrite bea

- Pete, et al. It really helps if you know the self-resonant frequency of the tower. ON4UN goes into a fair amount of detail in his Low-Band DXing book. There are examples and graphs that may or may no
