[TowerTalk] Need Relay Replacement Help

[Joe L Blackwell]

Hi Dennis,
This sounds like the parasitic array I ran on 40m for years.  It was in
the 1977 Antenna Book.  Nice arrangement.  I used fairly heavy relays, 25
amp contacts, always 1kw output.  Think I still have a couple of those
relays around someplace.  Double pole, double throw.
Any relay you can find with contact rating of 20-25 amps would be
sufficient.  Relays in the Ameritron RCS-8V are rated 4kw pep below 30mHz
and they are quite small relays.
