T-6 & T-6G
'VHF' Line Isolator and RFI
The T-6 series of Line
Isolators are available in limited quantities. I have about 20 of each
available. I will no longer build them because I don't have the parts.

RTTY or other high duty-cycle modes.
|The T-6G is the grounded version of the
T-6. It provides a direct path to ground so that RF traveling along the coaxial
cable doesn't see a path back to the operation position. A very effective way
to eliminate RFI leaving or entering your radio room.
A VHF LINE ISOLATOR?
Yes! Even at VHF, you will find
the T-6 as useful as the T-4 is on HF. The T-6 is perfect for use with vertical
antennas of all types. Why put up a terrific beam with a good front-to-back
ratio and then let feedline line radiation spoil the antenna's pattern?
Ground loop problems can still
be a problem on 6 meters and the T-6 can help eliminate them. What the T-4 has
done with RFI problems on HF, the T-6 will do the same on the upper HF bands
plus 6 and 2 meters.
The T-6 does it all!
The T-6 may be used in any Line
Isolator application. Beams, verticals, wire beams, RFI, TVI, equipment
isolation, the T-6 does it all.
You'll need a
cable to connect Line Isolators between equipment.
