1. [TowerTalk] Improving the Dipole/Doublet (score: 1)
Author: Lee A Crocker <lee_crocker@yahoo.com>

My suggestion is to throw a box of plant food around each tree in hopes they grow higher, and forget about improving the dipole. Put up a vertical to buttress areas where the dipole is weak. There is

2. [TowerTalk] Another tt40 Wilson Tower Query (score: 1)

Why would you knowingly put up a "self supporting" tower in unstable soil, and hope a few 2x4 toothpicks held together by a handful of nails, will make this structurally sound? It's the soil that pro

<I don't have a ready way to measure the inductance of each coil > Did you look at this month's QST? You can build what you need to measure this for less than a buck 73 W9OY _________________________

It is true the measurement is at audio freq, and it will not be the equivalent of a HP phase gain meter, or a VNA or other such device. For 160M, it will be better than determining inductance by (R^2

Mt question would be is the feedline acting like a transformer on 160 and not a transmission line? The second question is are you using some kind of lightening arrestor like a ICE arrestor in the lin
