Just set the antenna up this week. Can see it at www.qrz.com under home call
n0ah.
Questions for those who have one.
1. SWR started at 1:1 without radial of course and now with it tied into
Cushcraft 40/80 vertical 60 feet away of 50 underground radials, 20-60 feet
long, and 8 additional radials ranging from 20-80 feet, on the MA160V..... SWR
is now at 1.8:1. Has anyone experienced a significantly higher SWR at
resonance with a good radial field indicating the true impedence mismatch of
coax to antenna? I’m glad to see our’s rise but was wondering on this antenna,
where it might max out- Planning to use an UnUn to match it as we add more
radials if needed- My old inv. L went as high as from 1:1 to 5:1 when we got
120 radials under it-
2. We are averaging S-9 noise both during the day and at night, expected but
wanting to know if others using it also have a higher ambient noise level-
Since the antenna is resonant on band, expect the noise level but wondering if
our RF environment is over the average in noise- We live in the suburbs and
most of the bands are actually pretty quiet on noise level- so this seems
pretty high- We have a electric transformer near the antenna just in a box on
the corner of the lot near the antenna but Excel Energy came out and tested it
for possible RFI and it was clean-
3. Does anyone use the DX Engineering RX antenna array for the low bands on a
typical suburb lot for RX with this antenna. If not, what are you using for a
small lot for 160M? We are using a Alpha Delta B 30-160M sloper which is a lot
quiter but even with the high noise of the MA160V, it is hearing much more D in
the noise- so we are looking for an alternative 160M listening system but the
DX Engineering array seems very expensive- yet we don’t have room for much
else- Any suggestions?
Thx for any tips. We heard several EU’s during the CQWWSSB....was fun! You can
see the antenna installed at www.qrz.com under n0ah.
73 es TU for any responses-
