Yesterday afternoon Marcial EA2BDS and me went to a short activation of Ganguren EA2/BI-055 pretty close to our QTH’s. The goal was to test and adjust a G5RV jr. which I’ll install as base antenna. I have no place for anything bigger than it. So, with the usual setup,this is, 9 m. tall fiber mast and 5 watts, we made a sort of EU QSOs with good signals, plus a surprising QSO with Matt VK2DAG on 14 Mhz at 15:53z. He was 579/589, but I’m sure that Matt doesn’t need prop to make QSOs… He makes his own! Thank you again.
As result, the antenna made well enough, but it is clearly not the best one for “sotting” because of its weight, mainly the 450 ohm ladder. Just that was heavier than the full norcal doublet antenna.

Mikel, as a base antenna, you can purchase a pair of inductors (G5RV-IND from Moonraker) which fit at the ends of the half size G5RV and with the addition of 2.4 metres of wire (which can hang down) the antenna then becomes reasonably efficient on 80 metres. If you remove the coax and extend the 300 ohm ribbon all the way to the tuner it becomes a good all-band antenna. I agree, though, not a good choice for SOTA!

Hi, Brian and thanks for the info.
I’ve studied the option of bringing the 450 ohm ladder all the way to the window, but it was too complicated (27m. and some curves thru the front wall of the building, too visible) , so I’ve chose the worse solution of coax.
About the 80m band option, I’ve discarted due to the very noisy environment I “enjoy” here in the middle of a industrial city.
