I strongly agree with Frank, not necessarily because of RDF, which
measures against noise from all directions, but because of
I also experimented with phased beverages to EU from my location.
Separation was not huge - about 40 ft. Length was about 900 ft. I have to
say I was underwhelmed by the increase in gain. However, what is a killer
is the front to back ratio improvement. It does a fabulous job on 40 and 80
QRM in pileups and contests.

The other thing I have noticed with my BEV's and BOGs is propagation
mode can cause quite a bit of variability in RDF or F/B. Using other
than a local station for measurement can give inconsistent and confusing
results. Often the RDF on some gray line signals will not be as good
compared to

In a rural area with no significant man made noise, if you redesign a beverage
for better RDF when do you start to notice a difference?

Hello Kenny
I have been playing around with antennas and feedlines over many years
and have found that your ears cannot immediately tell the difference
between a 1 dB change due to fading, atmospheric noise variations, QRN
etc. I have had scalar and vector analyzers over that time to
Hi Kenny,
Over the past 12 or more years I've conducted numerous comparisons of
different receive antennas on the low bands. I'm fortunate to have
enough land to lay all of them out with adequate spacing and perform A/B
comparisons. I am in a rural area that is relatively quite although over

I’m considering upgrading my single EU beverage at 625’ (190m) to a pair in
echelon where will each be 550’ (168m) with 20’ (6m) spacing . The increase in
