I've been reading up on the Isotron Antenna's that are tuned to the AM Commerical Band. A week and one-half ago, we had a bad storm come through the Nashville area and did some damage to my 3 wire, folded unipole on my tower. During the repairs, my engineer, Dale Howard, found other problems with my tower as well.

Looking at this Isotron Antenna, this seems to be the answer for a "temporary antenna" while your main antenna is being repaired. I know coverage would be limited and the bandwidth probably terrible, but my question is using this with a solid state transmitter like the BE-1A be o.k. in an emergency situation?

They claim a 50 ohm feed, no radials needed, but I wonder about reactance and VSWR? For the money (if this works, like they say) would this be a good "stand-by" antenna for a 1 KW AM daytime station if your main tower went down?
