Do NOT miss out on Bret’s SurvivalComms Youtube Channel

By a strike of luck the SurvivalComms name is used by me and another guy (Bret) for his Youtube channel.

It also happens that we both are focused on practical HAM radio matters for Survival and Prepping.

Bret is not only knowledgeable but also good at breaking down matters and applications  into simple, layman’s terms. Among these are his DIY simple antennas.

So DO subscribe to his channel.

If you are an owner of Kenwwod or Yaesu handheld radio, or anyone that accepts a charging input of 12V, then you might try this:

One more DIY Groundplane Field Antenna version

Bret at the SurvivalComms Youtube channel (it is not me, just a name coincidence I did not expect) has built his own version of the Jungle Antenna (Link 1, Link 2)

He uses a ring made from ABS rods to “hang” and position the ground wires, and the handheld’s radio own antenna. From the looks of it performance can further be increased with a telescopic antenna like the Diamond RH-770.

He also has a build of a discone antenna with the same method.
