la bobina di induzione si fà molta fatica a farla scorrere per fare la taratura e bisogna stare attenti che non vengano a toccarsi 2 spire alla volta.

Kan vara lite svår att trimma in men i övrigt en helt okej antenn för portabelt bruk.

This is designed as a 'go bag' portable antenna. My little bit of testing has revealed that this thing, as is, is rather excellent as a ground mounted vertical for 17-10 meters. The supplied ground radials are a bit weak below about 20 meters. If you want to add some longer, better, ground radials this can perform as low as 40 meters as a good portable antenna. This, as is, will not tune below 40 meters. If you move the coil to the bottom, you may be able to tune 60 meters.I really enjoy the JPC-12 because it is like an 'erector set' for antenna experimentation. I did buy a second one and am having so much fun.The one i received was actually in a in a nice carrying bag. Mine shipped from China and arrived a day earlier than promised. The plus of the China shipping is that you can often save $20 on the price.
