Topband: Titanex

[David Cole]

Hi All

I have a standard 89 foot Titanex  which I use on 160m - can anyone help by running the following through a computer model to advise the theoretical improvement in efficiency if I increase the Titanex by 20feet. The vertical is tuned against 75 radials mostly 140 feet with at least 6 at 200 feet.

I have a spare first section of a titanex - so the additional height would be made by 20 feet of approx 3 inch diameter tube.

Many thans Dave G3RCQ
