Slim Jim vs. Traditional J-pole Antenna

Measured gain of SlimJIM and J-Pole

Real measurements of a Slim Jim antenna and traditional j-pole antenna reveal the truth about their respective gain and pattern.

Small Loop HF Antenna

With components from a variety of vendors, custom machining and a bit of trial and error, another variant of a small loop HF antenna is born.

KX4O 1B-Battery VA Field Day 2015

The 20m AHVD and 40m small loop antennas during KX4O 1B VA field day.

Despite a weak battery and few contacts, our 1B-Battery effort verifies a 40m small-loop and packet-radio NTS messaging using quick deploy antennas.

Cutting Copper for 6m LFA Yagi

Use a torch to solder the loop. Be alert for air expansion pushing the joints apart.

Here is a step by step photo album showing how I prepared home center copper pipe for use in a three element Loop-Fed-Array Yagi-Uda antenna (aka LFA Yagi Antenna).

Low Profile Vertical HF Antenna

With the upcoming solar cycle pushing operations on the HF bands towards success on 20 meters to 10 meters you might be wondering if a vertical antenna may be the right choice for making the most of this time.

Well, to be honest you may well have just as much success with a simple horizontal dipole strung up.

Dipoles are pretty easy to build and don’t cost too much if you would rather purchase one from Alpha-Delta or the Wireman.

However, if you…
