The JPC-12 is a full kit to set up a resonant 1/4 wave vertical antenna including a case to keep all the components in, making it ideal for portable operation.
Covers a total of 8 bands from 7MHz all the way up to 50MHz (40m through 6m). Some users have even reported getting it to work on 144MHz by using just the fully collapsed whip (without the coil or extension rods).
it’s incredibly quick to deploy, you just drive the ground spike into the earth, screw the various pieces together, adjust the coil position/whip length to tune, and you’re on the air. Not all bands require the use of the coil, so you can either move the slider to it’s highest position (which essentially bypasses it), or leave it out entirely.
The extension rods are a nice addition – these raise the coil up away from the ground, making this a centre loaded antenna, which offers increased efficiency over a base loaded antenna.
