So, Cecil, I think you need to erect a simple 75 meter dipole and a coax
switch. See what the other guys says about your two different s meter
readings on 75 meters.

No need for me to do that, Michael, since Tom, W8JI, has already done it and reported the results. He had an A/B switch between a 1/2WL 75m dipole and a G5RV at the same height. He ran two tests:

1. He told the truth about which antenna he was using for the QSO. Most of the hams on the other end of the QSOs agreed that the 1/2WL dipole was superior.

2. He lied about which antenna was which. Most of the hams on the other end of the QSOs agreed that the 1/2WL dipole was superior. But since W8JI lied, they were really agreeing that the G5RV was superior. Were you one of those hams?

No Cecil, I was not. I also would have given my s meter readings
regardless of what I thought it should be. It is important to me to give
my fellow hams as much good data on their antenna work as possible. I
also agree that the hams that are asked about which antenna is sounds
better should not know which antenna they are rating. I have a friend
who has an inverted V dipole at 200 feet and a double bazooka as an
inverted V at 75 feet. He is 100 miles away and the lower antenna is
always the biggest signal. This does not make sense to me, but that is
what is actually happening. The angle of both antennas are the same. We
always need to measure actual performance and not paper performance.

I still think you should do this yourself. Just ABing the receiver is an
important test. G5RVs have a reputation that I cannot personally confirm
of being noisy. I do know for certain that some antennas produce more
noise than others.

My loop does a wonderful job of nulling out the noise from my
neighbour's homes and local industry.
