** THIS IS AN INITIAL EVALUATION WITHOUT COMMENTS

The DC antenna is nestled between a metal fence and a building, only has visible view from North East to South, with a hill to the West

**The ‘Pulsing’ in some images is the effect of our local TV station on 137-144MHz @ 50kw

 The antennas were compared using  R2ZX and RX2 radios
