Hi folks,
I have had a go with the helical - I'm not sure if it's my particular qth, or
how I had it mounted (in the trees), I had trouble trying to get it to resonate,
even with a couple of radials.
I've had more success with my attempt at a GM0ONX trapped 'Inverted L' antenna
here:-

I have a weatherproof box where the coax enters, in here connection to the
radiating element and to a grounding rod with a couple of long radials run down
a large bank at one side of the house.
The radiating element is suspended from trees at one side of the house.
I'll often have a listen through the band, but mostly tx on data-modes (PSK) -
will have to drop in for a chat sometime!!
Regards
Matty
