I have never had any luck with short beverages, EWE's, FLAGS, low dipoles, etc. Total waste of time.

In 2010 I went to the Hi-Z 3, then the Hi-Z 4, and finally the Hi-Z 8. I hear stuff I have never heard before..

Since then I added a Waller FLAG on a 34 ft boom at 95 feet...

Best moves I ever made..

I didn't see any mention of a preamp.  Signals from a good Beverage are
typically 20-30 dB below what you'd hear from a dipole or a vertical.
Everything else you've done looks good.  Keep it up!

"Beverages just want to work" is what I have heard.

Not having much luck with that here.  I suspect operator/installation

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
   *   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

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....
