For the last few years I have just been matching my topband vertical or inverted L antennas by using a 1:4 UNUN I have just seen the following article by Jay at Array Solutions.. http://www.arraysolu

To model this in EZNEC I put the source in the lowest current segment. The ground loss R can be in the next segment. The shunt inductor is olaced in the lowest segment as a load with *Ext Conn* set t

I'm with Gary on this one - and ON4UN. Making inverted L and better yet T-top loaded verticals too long will raise the maximum current off the ground and reduce the current in the ground system - bot

Dave, I have two concerns. 1. The ability of EZNEC to properly predict the impedance of your vertical, without you having to actually measure it and "warp" your model to mimic the real world. 2. How

I would just like to thank all who have replied both on and off the reflector. The discussion has resolved a problem I have had for many years, so I am very grateful for that. I have now done some us
