Topband: Shunt-Fed tower how-to Video

[John Chappell G3XRJ]

Steve,

That's an excellent video.
Both in the technique of shunt feeding and the overall video 
presentation which sets the bar.
Most impressive.

> This week I added a second gamma-wire to my shunt fed tower for 160m in order to lower the reactance and therefore lower the voltage across my matching network.  This winter I was having some flash-over problems.
>
> While doing this work I decided to make a video that explains the method for finding the 50 Ohm point on a tower, and the effect that wire diameter has on the SWR bandwidth and reactance at the feedpoint.  I show how I use both the AIM-4170b and the AR 55 zoom analyzers.
>
> I wanted to post the link to the video here on the reflector because over the years there have been a few questions about how to shunt-feed a tower, and this might answer some practical questions about how to go about it.  Maybe someone has a summer project in mind to turn their tower into a TX antenna?
