[Lowfer] Isolation Transformers

[Les Rayburn]

I'm in the midst of relocating all my receiving antennas
to the back part of my yard, the furthest distance possible
from the house and it's noise sources.

Rented a ditch witch over the weekend, and ran trenches
that are 16 inches deep running all the way from the
shack to the three main receiving antennas:

1. LW/MW Remote Tuned Active Whip (150 feet from the home)
2. 4 Foot air core loop, remote tuned on a rotor. (170 feet from the home)
3. 50 Foot EWE antenna, (150 Feet from the home)

The "T" transmit vertical (used for both HF and the XMGR beacon)
also had it's feedline replaced and the new one buried in a trench.

All cable is burial grade, with coax being 75ohm RG-6 quad shielded.

Some on my AM BCB DX list have suggested installing 1:1
RF isolation transformers such as the Mini-Circuits T1-6-X65 on
the receive antennas. This will be fairly easy, since in all cases
amplifier power, and tuning circuits are sent to the antennas
via a separate four wire cable.

As I understand it, I'd need to install virgin ground rods (already
done this too) at each antenna location and then use the isolation
transformers to keep them separate from the station's main
ground.

Hopefully all this will reduce the suburban noise levels here...

Any thoughts on the use of isolation transformers with these
antennas?
