Title: Antenna Switch
Post by: flintstone mop on September 15, 2007, 10:54:45 AM
Hello All,
I was wondering if there was a remote antenna switch? I could switch antennas from the shack. I don't want to buy 500 feet of coax. I hope to add two more antennas out back. Thanks
Fred

The four position Ameritron switches through the coax.  The 5 position needs a control cable, more expense.

THanks to all. There are many of these by more manufacturers than I thought. Now to make a decision........

i use the 5 position ameritron.  i burned up 2 of the 4 position jobs.  If you look close at the specs the 5 position is good for 5kw large open frame relays and the 4 is good for like 2kw.  not that your gonna run that cuam muaw but if you are using any non resonant antennnas like i was youl want to look at the 5 position.  i use direct burry cat 5..  I had 1k feet leftover from a job but you can get it for about 15 cent a foot.. or stop your local phone man  5 pair burry drop comes in 833 foot spools and the last 150 foot or so gets thrown out.  I was always happy to ditch the stuff off my truck in the woods...... in my back yard.
