Review of Pracomm SML-1000-1 HF Loop Antenna (# 95)

Roberto Arranaga, KX4CY, felt that commercial small HF loops were too expensive, so he’s made his own for sale at www.pracomm.store which has an interesting tuning method using a wide range tuner (such as the MFJs). I tried it and it works! And the price is right, too, at US$199 (introductory) plus S&H.

Discusses the difference between Yagi antennas, log periodic antennas, and phased array antennas. Also, I’ve picked up a sponsor, JLC Printed Circuit Boards, www.jlcpcb.com. This is the first time I’ve had a company sponsorship! Thanks to my wife, Loretta, KBØVWW, for reading the short advertising copy.

Review of MFJ -9232 QRP Mini Loop Tuner (AD#90)

This week’s video takes a close look at the MFJ-9232 QRP loop antenna. Given sizes of components and all, it is rated to handle no more than 25 watts. It can be used both indoors and out. This is a great little adjunct to those who want to play with (er…I mean “study”) loop antennas.

Review of MFJ-1984MP End-Fed Multi-band Antenna (# 89)

This turned out to be one weird antenna. It’s an end-fed multi-band antenna that’s best used in a portable environment. I had to get MFJ’s help to figure out what was going on; I provide all this info in the video. This is the summer of antennas! I learn new things every day! (I skipped a number–#88 is coming).

MFJ-6120 Zepp and MFJ-6220 Collinear Review and Test (# 87)

These are both 20 meter single band wire antennas (also available for other bands). This video reviews the “how it works” followed by tests for each, and explains how I got the Zepp to work. I particularly like the collinear (and, yes, it’s spelled with two L’s), which performs significantly better than my station vertical.

Making and Using a Simple 40-m Dipole (#86)

I’m often asked how to make a dipole. In this video I use materials on hand to build a 40-meter amateur radio dipole. I hung it on the antenna test rig I built this past week, and it works great! Lots of work, though. Although dipoles are available for far less than $100, I made this one for zero!

Setting up to Test Wire Antennas (#AD 85)

I have several wire antennas ready to test, but needed a couple masts. This video describes how I used chain-link-fence top rail together with pulleys and guy rope to set up the “test range.” This is an easy technique you can use to set up a dipole when there are no ready supports.
