Topband: Help Needed Decoupling the TX Antenna

[Eric Rosenberg]

My noisy urban lot is small (40x140), and the Pennants are awfully close 
to the TX antenna. (inv-l's on 160 and 80, 1/2 square on 40).

I need to decouple the TX antenna when listening on the Pennants, but am 
not quite sure how to do it.

I'm using a MicrokeyerII for the radio and a KD9SV DXpedition 
preamp/antenna switch/front-end saver for the RX antennas.

Once I get this straightened out, I'll be sure to work all of you who 
heard me but I didn't hear in the CQ 160 and ARRL DX contest.

Any help is appreciated!
