Two of these big boys sure makes a difference. The NCC-2 Preamps are also excellent!
WOW – two of the same type of antennas sure makes a difference, and also – the 3/4″ copper is way better than coax for the elements – and these blow the W6LVP Loop out the door. The nulls are sharper, the small distant stations are much louder – all around this setup is what I had hoped it would be.
The NCC-2 preamps are very low noise, and it will be very interesting to see if the Wellbrook ALA100LN preamps do a better job. At this point, what I have going here is a big step up from what I had up before, so it being even better would be icing on the cake.
I just checked my Inverted Vee and UrbanBeam – and none of the weak small market and low power stations in Oregon could be heard – S Zero. Turn on the phased loops and the signal is S7. That’s an improvement of 36 or 42 dB! (I’m not exactly sure). There are some big QSB fades – but that is when other stations start coming in. However, the phasing knob really has come alive – the new problem is selecting one of more stations than I could hear before – but with the attenuators, balance and phase controls – there is always some combination that works – and sometimes turning off one of the preamps is the answer. The deep fades do not last as long as they did before – so that’s great.
One of the things that is interesting is that EZNec had two of the KY6R Optimized 40M Loops as stellar performers – better than these two Big Mag Loops, and the reality is that in practice – its inverted – the Big Mag Loops “run rings” around the Delta Flags (bad pun intended).
The cost? Pretty damned low – I built two loops for $80 for the copper tubing (half what you’d pay locally at a plumbing supply store) and then $30 for all of the other parts – junction boxes and fittings. The wood cost about $30 – so a total of $140 or $70 a loop. The big cost is the rotators and the preamps.
