[TowerTalk] Second antenna options?

[Mark Robinson]

I will give the sloper my vote. I am using a sloper which is bonded to my 86 
foot tower at the 72 foot level. I have 4 wires on and can cover 1.8 to 1.86 
(approx) , 3.500 to 3.850 (with a 1.8 to 1 swr or better) and also 30m. I am 
getting an interaction between the 30m and two 80m wires I think and I may 
be changing the 30m wire for a 60m wire.

This has proved to be a very effective resonant antenna for me.
