Carl,

        I know that you won't be surprised that I missed the need
for two rather than one relays ... sigh.

        I'll either have to get two of the ones he recommends:

        Or find another matching Leach.

That relay is fine for switching coil taps but doesnt appear to be what
you need unless you wire sections in parallel and use a relay for each
band. Since youre switching at a low RF voltage point the main concern
is RF current handling and that relay looks to be overkill.

I recently acquired one of these 3PDT relays:

I have an application to cold-switch sections of coil inline with
my 43' ZeroFive vertical to help with tuning on 160 + 80m.

Anyone know if this relay would be suitable to the task at full
legal ... or for that matter for RF in that application at all?

Thanks ... David KD4E
