First Impressions: Pixel Pro-1B Magnetic Loop Antenna

rotate-loopIt’s been a pretty busy week or two at the QTH. Between the big photo shoot (more pics to come, I promise!), post-production work, a class reunion, and Stanley Cup hockey, I haven’t had nearly as much time in front of the radios as I would have liked. That changed a little yesterday though when the FedEx man dropped off my new antenna: a Pro-1B magnetic loop antenna from Pixel Technologies.

If you’re unfamiliar with magnetic loops and how they work, check out this video from Pixel technologies on how they work, and why you might want one if you live in a noisy urban environment. I am fortunate though in that I live in a small town, and don’t have a lot of noise sources to contend with. For me, the big attraction is directionality. With a cheap TV antenna rotor, I have a rotatable, bi-directional antenna that requires very little in the way of a footprint or or support. In my case, this antenna is basically mounted to the corner of a chain link fence about 10 feet off of the ground. No guy wires needed, just some pipe clamps and a few cable ties.

I’ve only had a chance to play with this antenna for a couple of hours, but so far I am very impressed, and somewhat surprised by the results. I was not expecting the signals to be as strong as they are using this loop. in fact, the signal level is almost identical when compared to my long wire. I was also somewhat concerned by the antenna’s proximity to the chain link fence, and whether or not it would adversely affect the directional performance of the loop. I’m happy to report that is not the case at all. While I suppose performance could be even better if it was in a more isolated location, this antenna is capable of reducing the signal of WHO, my local 50 KW flame thrower,  by about 30 dB. Other experiments, which I tried to commit to video, show how this antenna can be used to null out a local ‘graveyard’ station KASI on 1430, reduce the signal of Radio Nacional da Amazonia on 11780, or separate Cuba from Radio Australia on 6150.

All in all, I’d say this antenna has made a heck of a first impression. It not only holds its own on signal strength with my long wire, it gives me an element of directionality I didn’t have before. All in all, I’m looking forward to having this antenna in my DXing arsenal.
