An antenna is the most important part of the Ham Radio station. The more effective HF, VHF or UHF antenna, the longer distance contacts could be achieved.
In this video, I build and test a VHF/UHF antenna for mostly FM communications known as a J-Pole antenna. I was inspired by the article in the QST Magazine February 2003 by Edison Fong, Amateur Radio operator callsign WB6IQN. I adopted this antenna for my needs and frequencies I use most on 2m and 70cm amateur radio bands.
I have also designed few 3-D printed parts for this antenna, which STL files could be available for free at printables.com here:

Enjoy building and using this antenna!

I really like the performance of DeFong antennas. I use mine for several operations including bike events for APRS and coms.

Excellent explanation ! It looks quite complicated but I am sure then end results are good.

Nice Video! Just an Idea, for another video: Show your Ham Radio Van. I'm very interested to see the interior.

Thanks! My Radio Van is covered with snow at the moment :) But I will make a tour-de-table video when the weather permits… 73! Merry Xmas! Linas LY2H

I just got some surplus 300 Ohm twinlead (for free!) at a ham swap, and I already have a lot of RG-174. So now I can make several of the Ed Fong DBJ-2's to hand out as gifts to other hams. I'll make some roll-up versions and some 'stick in a plastic tube' type. It's nice to finally be retired. :)

I have and use a commercially made roll-up J-pole antenna for 2 meters. It works well, and I keep it in my pack for portable use. You have inspired me to make your design mounted in a pipe for use with my van when parked. There is always more satisfaction with something you build yourself. DE WA1KLI
