"Beverages just want to work" is what I have heard.
Not having much luck with that here. I suspect operator/installation error.
I did a lot of reading and I must be doing something wrong.
* 250 feet of insulated wire strung out in 030 degrees direction toward EU,
pretty straight, varying in height from 4 to 6 feet, running through thick
brush with no metal objects or artificial elements along the run.
* 9:1 transformer at feed point with ground rod
* 300 feet of coax, mix of RG-8, MMR-400 to get to the edge of the woods
from the house
* No terminating resistor
On bands 160-40, the signals are very weak. I am monitoring WSPR, FT8. I can
hear signals on 160-40 but they are way down compared to dipoles and inverted L
on the same bands. Like 20-30 db down. From what I read, I should NOT need an
HF pre-amplifier, right?
Signals on 30 and 20 seem to be better and I can copy some DX from EU on FT8.
I will try installing a new ground rod, the old one is 10 years old and perhaps
not making a good ground connection at the feedpoint. The transformer is
brand new, so that's not an issue. The coax has tested out fine. Soil is
central North Carolina clay, a bit dry at this time.
I am guessing performance is poor on 160-40 because of the short length and
that it's bi-directional (no terminating resistor), which I am seeing on 30
meters. But I did not think it would be THIS bad on 160-40....
