[Lowfer] WA back

[Bill Ashlock]

WA was returned to service about 3:00am this morning. Test results on the RX 
Tree Antenna indicate a gain of about -20db but the SN across the band 
appears to be better than any Lowfer antenna I've tested. No neighborhood 
light dimmers or computers could be detected, which is my normal limiting 
factor here in suburban country.

Tonight I'll install a ferrite stepdown transformer out at the antenna to 
allow a much better match to the receiver and line. Figure this will give me 
about 6db more signal. The final testing will be to A/B compare the SN 
against my existing amplified loop using two separate lines and a switch in 
the shack.

It was interesting to note that my portable SVM could copy weaker signals 
with this antenna than the R-75 and must have approx 6db better MDS.
