Hello and HNY! I will be converting a wire inverted-L to a T top loading on a 75 tall wire hung from a tree. To improve the bandwidth, I was wondering about going to a 2-wire cage for the vertical se

Hi Clive, thanks for the input! The existing 75 foot inverted L measures 26 ohms X=2 using 60 x 100 foot radials. This is very close to what the model calculates. Regards , Kenny K2KW _______________

Most if not all replies were off line, and thanks to all who wrote in. 2 key ideas came out: 1) try and reduce the height of the leads at each end of the beverage. But they are not exceptionally high

Hi Karl, yes CMCs are easy and should be installed regardless. Even if they dont help with 40/80, they will likely help on 160. Thanks for describing your experience. Regards , Kenny K2KW ___________
