Larry Plummer, W6LVP out of California, offered me the chance to test out, review, and let others know what I thought of his Active Receive Loop Antenna. Check this beauty out:
Loops are fascinating antennas for the amount of signal they can pull out considering their electrical size. This loop, being an active loop, contains a ‘low-noise amplifier’ right at the feed point of the antenna to magnify signals. Its widely known that loops can be used to null out noise sources due to the sharp deep nulls these antennas possess broadside to the plane of the loop. Loops also have a few advantages over antennas like verticals because there is no null directly above the antenna.
Granted if you have the ability to put up a full size antenna, and you don’t fight with noise, then an active loop might not benefit you much. My goal is to test this loop from a ‘Suburbanites’ perspective living here in my cramped HOA and fighting all sorts of noise sources. The lower bands are particularly difficult for me to even just listen to. That’s where i’m hoping this loop will shine once I get the ability to mount it out & open in the clear! (Might be a few days while the storm passes through)
Pictured above is the power inserter that Larry provides with one antenna package, the other package comes with the transmit/receive switch (pictured left) that allows you to combine your transmit antenna (and even an amplifier) with this setup making a very power receive/transmit station!
I’m looking forward to attempting multiple different scenarios with this antenna and putting it through the rounds! Starting tonight with indoors reception on WSPR! Eventually it’ll make its way outdoors onto a mast.
This loop is sold at a much more attractive price than the Wellbrook or RF Pixel. The MFJ active loop is closer in price, but it’s a solid loop, and the MFJ loop appears to have a higher noise level based on the reviews & videos i’ve seen online, but over the coming weeks we’ll find out just how well this one performs!
If you want to find out more about Larry’s antenna, please visit his website. Or checkout the great eHam reviews. A full video review & blog post is on the way for this guy, but not until i’ve had plenty of time to experiment!
Big thanks to Larry again!
