Re: [SPAM]Re: [CrossCountryWireless] Antenna Isolator install
The antenna and loop counterpoises are isolated from ground. The wire in the loop counterpoises is insulated and is laid directly on the ground to couple capacitively to ground.toggle quoted messageShow quoted text
The existing ground radial system was removed and replaced with the loop counterpoises.
If you were to use or follow the transformer design with the capacitors to counteract leakage inductance in the transformer it has an excellent match to 50 ohms so would work with the matching stub on your feeder. If you have already spent a lot of time optimising the tuning of a multiband vertical the transformer can be connected in circuit with very little difference needed to the antenna tuning. There were no changes needed on the two antennas I built to test the design.
