Well, I went out and both grounded the loop to the shell of the BNC
connector and also tried grounding it to a ground rod I had put in
previously. The results were......... No change. I had my G313E
set to pick up WWV on 5000Khz and was doing screen captures in-
between each test and honestly couldn't see any difference, either
in the signal levels or in the noise floor. Nothing, Nada, Nil.
Before you ask, I tried grounding the tube at 45, 90, and 180
degrees and lightly sanded it so a decent connection would be made.
I also checked on the screws because someone here had said that they
had an ALA-1530 and the Aluminum loop had a couple of screws in it
about 2 cm from the loop base. There were no screws or holes to
indicate missing screws either. Hmmm. Either this person was
trying to describe this Antenna from memory or he has some other
kind of loop. I can verify that I have a Wellbrook ALA-1530
(Standard version) that works quite well. (If anyone wants to come
see it or or my ALA-100 setup, you're welcome to come.) The only
screws I could see were actually in the plastic antenna base and
they were sheet metal screws used to secure the aluminum tube to the
plastic, which I don't think could also be used to secure wires to
the tube.
