I have installed a receive loop ( http://www.qsl.net/kc2tx/ ) and finished measuring and observing...
Measurements: VSWR --- 1.7 @ 1.830 ZO ----- 77 at 1.830 Observation: Following ON4UN's comments regarding needing a preamp or not, measured S1 to 2 noise level with antenna connected during mid-day, S0 with dummy load connected. During evening hours, notice some improvement - S2 drop in noise level when switching from xmt antenna (inverted U) to the loop - but not hearing much in the way of receive signals (e.g., hear a fairly strong signal from the west coast on the xmt antenna, nothing on the loop and I have it oriented east/west). I'm uncertain if a low noise amp will help my cause (thoughts??) I do not have a common mode choke installed, yet...will one make that much difference? The loop is located about 60' away from the Inverted U and radials. Comments/suggestions appreciated. Thank you, in advance, for constructive, relative to what I have now, replies....non-"constructive" means I can't erect a BOG, Beveridge or Waller Flag so don't ask why I didn't go that route. 71.5/72 de Jim Rodenkirch K9JWV _________________ Topband Reflector Archives - http://www.contesting.com/_topband
