1 - The RME is a DB-23.

2 - I know it only covers the Amateur bands.

So I am going to look at the circuit in the Johnson T/R Switch. (250-39)

It is a constant across the entirety.

Tom,

Every time I even think about trying something along this line of 
thought, I get a very "itchy" feeling.

The reason is that my attic has somewhere around 18" to 24" of blown in 
fiberglass insulation!

It is even stapled on the cover that accesses the attic.

Now if I could only figure out a method to avoid all contact with that 
stuff.

It was already about 6" to 9" deep when we moved in in 1988.  We added 
more to reduce the insane electric bill.

I need something to be able to reach up to the rafters remotely.

I've done a couple of loop antennas that were even smaller, only they 
had no amplifier.  It looks fairly simply, and perhaps it will stimulate 
some thought as to how to get one up there.

I wonder if an RME-DB-23a would be of use?
