Galco is months-out before they have stock.

Array System wants nearly $50. shippped.

I'm thinking of looking for a reasonably priced set of
one SPST & one DPDT - sorting out acceptable specs online
is a challenge as most 12v 30A relays are not rated for HF.

This is to switch-in and out additional inductance at the
base of a 43' vertical for 160 & 80m.

It will occasionally be challenged with a 1KW+ (PEP) amp.

I was directed here:

###  Does it have  to be a 3PDT ? Is this for a TR relay in an
amp..non qsk of course ? What bands does it have to operate on.  Huge
difference between 80m....and 10m.

##  You need a relay that will handle 20A  of RF..at the highest freq
you operate on.

##  If this is for the output of a linear..a better solution is to
use paralleled Gigavac  G2 relays.   That combo will handle 20 A  CCS
on 10M band.  Sped up they will operate  and RLS in 2.5 msecs...so
they can be used qsk.

I need a 3PDT RF relay rated for 15KW or better.

Is the $38.95 Array Solutions relay the best, perhaps only, option?
