[TowerTalk] RCS8V 5 pos switch and alternate relays

[Allan G. Taylor]

This is a follow-on to the comments re the MFJ RCS8V 5 pos remote antenna sw.
I have used one for about two years to control a K1WA-type sloper array (40M).
My experience is that one of the 5 relays will occasionally not make contact but
that a few passes with the switch will clear it up.  I know that the K1WA array
should have both center and shield switched, but the array I put up still gave
some gain and f/b ratio (and a big signal!). My next project is to redo it as 
a 6-el sloper with both directors and reflectors in addition to the driven 
elements. That won't work with the RCS8V, needless to say, and will require a 
homebrew relay box and 12 relays!  Can anyone out there suggest a good source of
usable dpst and spst relays suitable for switching a legal limit at 7 MHz? (NO,
not under load!) I prefer 12 V relays and not so fancy that I could buy a yagi 
for the cost of the relays!!

If all this works out, the RCS8V will be for sale!
