Ken,
 
AA4NU's input is the better one, and really the most cost-effective  for a 
quality unit(s).  On that Top Ten site, if you go to  Application Note 4, you 
will see the "simple" crossover  arrangement that uses two of their AB 
switches.

There are some crossover surplus relays out there, but the prices  shown are 
quite high. I was fortunate enough to find this exact Amphenol N  Transfer 
relay for $10 at a hamfest a few years back.   Doesn't help  you now, but keep 
an 
eye out at the bigger events.

Subject: [TowerTalk] Antenna crossover  switch

Does anyone know of a commercially available antenna transceiver  crossover
switch (like the MFJ-1703), that will handle 1500 watts. I have  googled to
extreme and found nothing.
Thanks,
Ken  W7TS
