An EASY Antenna for HF - F-Loop 3.0 | K7SW Ham Radio

What would a Magnetic Loop Antenna do for you ?

Thorough and informative. Sufficient objective detail to help someone make an informed decision. Nice.

I just received my two piece aluminum radiator kit for my 3.0 today. I figured I would watch your video again to see how it goes together. The directions are okay but it’s nice to see how someone else does it. Thanks for the tips!

Professional presentation, good job. I've used both homebrew and commercial loops over the years. They work well as long as you understand the limitations, mainly bandwidth.

I have the Chameleon PLoop and it is fantastic I use it from inside my apartment and it works Great from inside! If you live in an apartment or HOA nothing can beat a mag loop!!!

Squash the smaller Loop a little bit. Increases the output. KG7IRJ Ohio

great review of the mag loop antenna, I can see this being the perfect antenna for an apartment

I hadn’t thought about laying it on the table to set it up. It’s great for taking to the cabin when it’s too windy and cold to set up an external antenna. Great video. VO1OK

First time I tried a loop antenna was using the MFJ-935C and 4 meters of 10mm copper pipe, 20 meter band and 20 watts made contact with a chap in Canada from Ireland, I was blown away, this thing was sitting on a patio table !!! 4 meters of copper pipe is probably more efficient than a 2 meter loop and you have to use different size loops for different bands but probably adds to the efficiency, either way a very cool antenna system to experiment with, can take up to 150 watts too. I don't have a chameleon loop but I do have the MPAS 2.0 with CAP HAT and love it, great antenna.

Great video. Thanks for taking the time to film it.

I’m glad for this video because I wasn’t sure if something was wrong when my knob was that sensitive. It seems like it’s normal to have an extremely narrow bandwidth and a really sensitive variable capacitor relative to that bandwidth.

Best Mag Loop demo on YouTube, thanks for putting it up! K3GM

Wohooo-... I could hear my big Radio Buddy Barry, N4WFU from NC-State. How awsome is that? 💯👍👍👍🙋‍♂

Nice review - thanks! I'd like to get a mag loop sometime. At the moment, I have no shortage of trees or space so I don't really need one. But having an indoor and/or easily-portable option is appealing.

Thanks for the well-done review. I bought a PreciseLoop SOTA magloop a couple of years ago. It's been deployed on several SOTA and POTA activations. It is best for running a frequency, although with some practice, you'll figure out where you need to be on the tuning capacitor quickly. It is not very efficient on 40m, but gets better as you work up the bands. It is easy to deploy and does not take up much room. I like them. But they fit into a continuum of antennas for portable ops.

I’ve always wanted a Mag Loop… i could have bought a nice MFJ at a Hamfest years ago, but didn’t… it seems easy enough, and HiQ seems perfect for qrp. Thanks for the video.

Ok, now you’ve done it. I’m gonna have to drag my homebrew loop out of the shed & put it on the air next POTA run ;-) 73 de W8IJN

Awesome. Very helpful video, in general....and great review/demo video to boot. Thank you, Sir.👍

Just a tip: The KX2 has a "TUNE" feature (press and hold the "XMIT" button to activate) in which it will transmit a continuous CW carrier until you press the button again. This is really handy to tune an antenna or even to just check the SWR. By default it will use the normal output power but you can set a separate (lower) output power level in the settings under "TUN PWR" that's safe to use with a high SWR.

From what I have heard about these, if you have it vertical, like in the video, it is directional off the sides. If you put it horizontal, it is omnidirectional.
