[TowerTalk] Shared Apex Loop SAL-30

[Fernando González, EC1CT]

Krish and Gary,
The white coating is just a special marine grade paint for fiberglass. We 
did the same manner as with the SteppIR elements that have been handling the 
UV radiation up there at 4000 fts pretty well for many years. Regarding the 
trasmitting antenna, it´s just an inverted L (45 ft high, rest of it 
horizontal). This antenna is sharing partially the radial system of a 
quarter wave vertical on 80 (you can see the vertical on the video on the 
images from the drone not far from the 4sq for 40). The inverted L is pretty 
noisy and I got some bad feelings about its performance (poor ground plane) 
but Oscar DR holds the DXCC on 160 with it so who knows. Krish, you´re right 
about the comparision but I can assure you the FT4 was cero nada nil on the 
inverted L and not only because the noise...You got a video on youtube 
comparing the shared apex loop vs a circle array which is certainly much 
more accurate. The antenna really works but I don´t have any other antenna 
on recepcion to compare with. The transmitting antennas (at least the 
inverted L) cannot be compared and can´t help as it´s mostly useless for 
very low DX signals-

Also would be great to watch a comparison between the Tx
antenna and The loop. Need to
be able to hear it first before playing
With Front to back etc.
