Transformers for low-bands antennas
These transformers, they can be used as part of a hybrid combiner or as phase inverters for an RX antenna array
Triband Receiving Loop for 160/80/40m
The loop is the unshielded type constructed from RG-11. The benefit of the shielded type loop construction seems to be in loop balance and that is said to improve null depth

balun much simpler with two completely separate windings, in which the power cable braid is kept isolated and not connected to the antenna ground
Waller Flag Antenna
Most of the time there are no horizontal signals at 20ft high for 160m, the arriving signals are shorted circuited by the ground, Tests on 3.5 or 7 MHz shows a different situation and there are plenty of horizontal signals
