Hi there,

i'm thinking about build from scratch on the roof of my house a lightweight
random vertical antenna (with small pvc tubes or fishing rod) feeded by an
automatic ATU. The same antenna with some kind of leverage will be erectable
from 0° to 90° (plain to my *plain* roof) to avoid & prevent lightning but
this is a mechanical history... so:

Many posts about the Rybakov antenna reports the use of a 4:1 UN-UN. I'm not
sure about the real needs of this kind of un-un... you readers what have to
suggest about height and un-un if you have to build a random vertical to
cover 80-6 meters with a decent efficiency ??

TIA,
