[TowerTalk] Effect of element shape was: Re: InnovAntennas contact info

Steve,

Yes.  Take a look at the little mono banders we have on our website  www.cycle-24.com.

On many Yagi antennas you will see one frequency where there is huge front to back.  With these designs we have listed huge front to back extends across the entire band.  The antennas are modeled using EZNEC Pro/4 (NEC4).   Actual models built and installed show these results in the real world as best we can test them.  

Admittedly front to back, while a nice number to talk about is much less important than front to rear (difference in forward gain and highest gain between 90 and 180 degrees off the front).
