[amsat-bb] Polarity Switcher

Hello Amsat list,

I'm a new list member.  My call is AE6RV.  My radio is
an FT-726R with a couple of Mirage bricks.  My antennas
are: a turnstile on 2m and a turnstiled moxon on 70cm;
both in the attic.  I don't have any preamps yet.  I've 
been working just the FM sats lately.

I have a question about polarization switchers.  Right now
I don't have any and suffer pretty bad fades.  I seem to
be frozen by "analysis paralysis".  I'm thinking of using
the Omron G5V-2 relay in a simple switcher with the 
contacts paralleled.  As I'm running less than 100 watts
at the antenna this looks like a good choice.  Should I
be looking at something else?  My budget is limited, so
expensive relay setups are out of the question.

Bob - AE6RV
