JPC-12 Portable HF Antenna - Hidden Secrets

I picked up an aluminum disk with wing nuts all around it for ground radials, and ordered a longer whip, and a second loading coil. It will tune 80 through 6m with some manipulating the various parts

Thank you for this video Peter. I've had mine for a year and never even thought about trying the coil at the bottom.

At the moment, worked 72 DXCC (175 slots) with it. Including Australia, Indonesia and Brazil from Slovakia. My favourite antenna for portable operations.

Great review. Like the trails of all the possibilities of this antenna.

Good to see you and n the garden , finally!.

I have one of these antennas JPC 12, and also have the JPC 7. The JPC 12 vertical version, does indeed work very well, and it is a truly portable antenna. I also discarded the ribbon feeder, and replaced it with more substantial wire, but cut them to the same length as the original wire (ribbon feeder). At the outer ends of the radials, I crimped some `O’ lugs, this then enables you to peg your radials out under very minute tension. The pegs I used were the cheap and cheerful 3 inch wire pegs which can be bought cheaply online.

Mr. Waters, this is an excellent video as always. I am by no means a young man anymore, but I am still a young Amateur Radio Operator. I have learned so much from you in the last 2 years. Thank you for presenting these videos. I will buy this antenna and give it a go for portable operations. This hobby is so fun for experimenting. Thank you sir. Ed Cheek, KM4MMD

It does do 6M nicely, made my first POTA 6M contact a few weeks ago

Thanks Peter, great as usual

Twaskyou sr for all information
Blessings

Excellent! Thanks! 💐

I am using the JPC-12 on my car for 2 years now on static operation, working grate. 4X5HF

Thanks for the tip on the toroid for the coax.

You can put the 4 threaded pole sections UNDER the cable connector unit to raise the antenna off the ground with elevated radials on bands from 10m up!

Great review Peter 👍! The one I have is marked PAC-12, but it’s the same antenna 😉. Looking forward to seeing how you adapt it to a 3/8” mag mount ! 73 de Dan WD4DB

Purchased one of these in 2022 but it has sat in a draw in the shack since then, it maybe time to get it out now you've reminded me I've got it.

very interessting... thanks for the video. 73

I have one of these and it does work well. It does utilize metric threads which means I can't mix and match with some of my other portable antennas. That aside, I do recommend it as a nice portable antenna solution.

A 3/8 - 24 to 10 MM adapter is easily made with a 3/8 bolt and a 10 MM nut. I welded the nut on top of the bolt head and othre than rustng, it works fine. I also found a machined aluminum adapter on Temu that does the same thing for only a few dollars.

My question:
Is that a Palm Sunday palm, from last year or older?
I have similar.
Get a fresh one Sunday, I'll do the same.
Thanks for the video on a neat antenna.
Good to meet you.
