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.

Hello Fernando,
What is the white coating that was added to the fiberglass support tubes?
Is that just paint or something else?

Fernando,
Great installation ! I love his QTH. I wish I had that much area for
antennas, sigh.....
thanks for sharing

GM everyone,
A couple of days ago I sent a mail about the Shared Apex Loop SAL30 from
Array Solutions that Pedro EA1YO, Oscar EA1DR and me installed at
Oscar´s contest station up in the northern Spain mountains.
Here you have a video of the installation and some rx test Oscar did
with FT4TA. Hope you like it:

BTW: I´m the one reading the manual...hihi
