Shell Beach CM95 And 144 MHz Tape Measure Beam



Fred, KI6QDH loaned his 144MHz Tape Measure Beam for field testing here in Shell Beach this afternoon. My location is ideal for pushing antenna performance issues at near zero feet above sea level to include geography conundrums. I found maintaining line-of-sight with our local repeater was problematic. Additionally, we shifted our frequency to simplex 145.500 and Fred’s signal was full quiet however he did not hear my transmission.

I experimented with an 1/8th vertical and the 3-element beam neither antenna produced dissimilar results. Both, in fact, performed poorly between .05 mW and 5-watts into our local repeater. The next antenna adventure at 144 MHz while walking Radio Dawg includes operating in the direction of Avila Beach beaming south of Shell Beach.

Project instructions are available from W6AB, Satellite Amateur Radio Club as a download portable document file.
