[amsat-bb] Elk Antenna Question

[Daniel Cussen]

Get yourself a duplexer:

I am not sure which radios you should use but beware of de-sensing one
with the transmissions from the other.

If using two radios an arrow without the duplexer is the equivalent as
it has 2 feed points. And elk with a duplexer may work better than an
arrow with no duplexer as there is additional filtering in the
duplexer, which the arrow would not have, when using 2 radios.

So basically the elk has only 1 feed point, to use 2 radios get a duplexer.
The arrow has 2 feed points, and has an option to add a duplexer to
combine them to give one feed point for a single radio use. Having a
duplexer in line may help with de-sensing.
