In my original post of noise in the antenna I should have pointed out
that I have other antennas that I compare it to. The signal is the
same on most antennas, however ie. S-7 on my DX-Ultra has white noise
or not clear, on my DX-A I receive the signal also at S-7 but the
signal is clear....that is to say the DX-ultra has background noise
along with the signal...I think we call this Signal to Noise. Is this
an inherent problem with the DX-Ultra? The best antenna I use for SWL
is a 40M Loop made by Radioworks.com The DX-Ultra is 70' sloped to
about 20' I also use an MFJ-1024 I phase with my K9AY and that works
well. My DX-A is only 35' up but 200' away from the house with 100' of
the coax buried underground(100' above)....with antenna analyzer this
antenna tunes up on 1,660khz with no antenna tuner but is grounded..I
have also found this antenna good on the Tropical Bands with hearing
good signals from Australian Domestics. I am always looking for
improvement. I know about feedline and common mode..this is why I bury
my coax and use isolation Transformers on my beverage antenna. Do you
think a balun on the DX-ultra would create better transfer of signal.
I also use RG-213 which is overkill but perhaps different coax may
decrease the S/N....any suggestions will be well appreciated.
