I was thinking the drawing you posted would be more like a feedline except at a couple of 10 and 12m frequencies. Just a guess.
You may be limited to a windowline J-pole for 10m. You could build one for 17 and another for 20 and string them up in the trees.
It's hard to really say without being onsite etc etc.
Lost all your stuff in 2001 because of anal radio sis? WTH did she do? Give it to Goodwill? If you'd rather not say, I understand. I'm just curious about what people do and what goes through their mind when they are so RELIGIOUSLY dead set against something, especially when it's radio.
When I was growing up, I had to start hiding radios away from my parents because who the hell needs more than one radio? Right?
Turns out a distant uncle was a Zenith dealer in N. Africa when the Trans Oceanic was big in the 40s and 50s. This uncle ran a shop and charged batteries (for a price) for customers. The claim was that he was taking the good batteries from new radios the first time they came in for a charge and gave the farmers and other people who had to save for a couple of years to buy a radio in the first place, bad batteries that had to be charged much more often while selling off the nearly new batteries that he got for free to the police and military. So as far as my parents were concerned, radio was dirty.
