I have 600 ft reversible BevFlex beverages and recently I bought a used HiZ 4-8. Both are about 300ft away from a shunt-fed tower for 160m and 4 sq for 80m.
On 80m, HiZ has a better F/B and hears slightly clearer than the beverages. On 160m Hi-Z is deaf, with S/N at least 6 db below the beverages. A marginal copy on the Hi-Z is a clear copy on the beverages, and a marginal signal on the beverages is no copy on Hi-Z 4-8. Does not matter what direction. No big buildings around although some large trees. My verticals are wires attached to 18ft telescopic fiberglass poles. The noise level from Hi-Z is decent so the preamps must be working. All directions show the same background noise so probably the individual HiZ Plus amps are OK. The whole array had lightning damage before and was repaired by an associate of Lee. I have a triangular Hi array at another QTH, very close to TX antennas and large trees. It has old ANT amps (not plus). Its sensitivity was never a problem. Does anybody have an idea what could cause HiZ to be poor on 160 while being good on 80m? According to reviews, HiZ should be pretty good on 160m.
