I have a north-south switchable 21m high phased pair for 80m with 1/8 lambda
spacing. It is optimised for 3520 kHz, the feed -Christman-system was made
according to ON4UNs book and software. Measurements were made with a General
radio bridge 1606B, oscillator and receiver. The system has a

What else is around your verticals? Just the fact something is not resonant
does not mean it isn't a problem.
To my ashtonishment, vertical 1: 28-j328 Ohm and vertical 2: 12-j320 Ohm
both on 1825 kHz.
The vertical with the smallest radial system has the lowest earth
resistance (around
