Fall is the perfect time for hiking, it's not too hot and not too cold. Last weekend I took a day trip to hike up High Mountain in New Jersey and activate SOTA summit W2/NJ008. It's really easy to set up an HF portable radio and not a whole lot to carry up the mountain. This video shows how to get set up including how to hang the antenna in a cluster of trees and making contact with Italy.

How much power where you using?
What was the base elevation and how high into the tree did the antenna get?
Reply to this comment
We were using 100W. The elevation was 550m, the trees were roughly 10-15ft.

A great tutorial. Perhaps for completeness, you should mention that FCC rules require an operator transmitting on 20M to hold an amateur ("ham") radio license. Obtaining a ham license is fun, easy and educational: visit arrl.org to learn how.

Is the antenna and/or radio grounded, or is that not necessary for this type of set up? If there is a ground - where and how?
Reply to this comment
No ground is needed with this antenna. It is a par electronics EF-20.

Nice article. Especially the part about getting the weight over the tree. That's always where I have problems, too :-) I built a slingshot-fishing reel to compensate for my poor throwing skills...it helps a bit, but it's probably a bad choice for hiking; takes too much space.

High Mountain Park Preserve welcomes visitors but prohibits fishing, hunting, trapping, collecting, motor vehicles, aircraft, horses and unleashed pets, camping, fires, firearms, rock climbing, spelunking, and feeding of wild animals.
Sounds like a real swell place

Cool setup, Diana - the bright orange slickline and throw weight definitely look better than my usual dipole-hanging method, which involves a small fishing weight, invisible monofilament line, and a whole lot of swearing and searching after each throw. Would a small carabiner on the weight work better than tying and cutting the line, or were you concerned the 'biner would get hung up in the branches?
I love the SOTA idea, and am now daydreaming about activating some summits here in Western Massachusetts. Is there a reason you chose the FT-857 rather than the lighter (and less power-hungry) 817? In other words, is the extra power output worth the extra pack weight, or was it just a case of using what you had on hand?

This was a great video to watch. Great to hear all those DX stations on your FT-875d "in the field"...

Very good job Diana. I have been a Ham for 33 years and have never done anything like this. It makes me want to get out and try it too. Keep up the good work.

100W, no rf choke.. that's just dangerous, and bad for your solid state finals...
go QRP.

Great to see SOTA taking off in the US. I didn't have a favourite fashion nerd before, but I do now!
Thanks
