The MFJ-9232 is probably the smallest loop tuner. It can be used to. create a very compact HF antenna. hamradiostore....

I have this loop, got it as a gift but shamefully haven't used it yet! I must take it out and use it. I have the MFJ-935C and using just 4 meters of 10mm soft copper pipe bent into a loop I made a contact into Canada from Ireland on 20m with just 20 watts and today using 2 meters of copper pipe made contact to Belarus 2,223 kms on 20 meters using just 5 watts. I will use this 935C loop tuner a lot more than I have, same with the 9232.

Just wrap it around a Hulahoop and Bob’s yer. I use the MFJ 936C and wrap the #10 around the hoop. Other time I drape a big loop around the dayroom, trying it this way and that. Like others, I have made some stunning contacts I previously thought impossible for such an antenna setup-the most surprising from inside the house!

It’s worked pretty good for me. I’ve used it from 20 meters to 80! 80 was a surprise because I was only using 40 meter length feet. Yet it tuned. No qso but I did get reverse beacon contacts. Even made a vid on the 80 m part.

Good honest video. Reports seem favourable on eHam, too. I was left wondering whether this would be any better than a loop into my Emtech ZM-2, as the manufacturer's website says it can tune loops. I need to do some research. Many thanks, Chris (2E0FRU)

It was interesting to see the comment about how this might compare next to a mag loop... the thing is that this IS a mag loop (capacitor in the box tuning a single turn loop that is less than a quarter wave around). OK I think this has the less common "army loop" type match in the box compared to the more common gamma match or small loop opposite the capacitor but it is still a mag loop nevertheless. As such standard "mag loop" considerations apply:- a) if you are going to use it at a window have it "square on" to the window NOT flat against the glass... these things fire in the plane of the loop so flat against the glass fires nothing out and tries to put its energy into the surrounding wall instead. b) 8mm micro-bore copper plumbing pipe can make a great loop conductor (easily available from DIY superstores). c) The screen of co-ax can also be used... make 2 little so239 to the terminal post/wing-nut adaptors and you can even use your existing patch leads for the loop. Just pick one of the right length. d) NEVER use the auto-atu in the rig to tune these.... they should tune properly without the rig's ATU and their efficiency depends on being properly resonant so the rig atu doesn't really help. I LOVE mag loops... I fully accept they can be a bit of a compromise but if they are the only antenna possible where you are then they are the BEST antenna you can have at that time. For travel and hotel use they can be unrivalled (you may have seen my Rad-Com article about receiving with Mag Loops INSIDE cars). If you really want to be "secret squirrel" on holiday and have a large old hard plastic suitcase with no metal in it then you can get a mag loop for 10, 15 or 20m inside it. Sitting with a portable rig in your lap and a suitcase sitting on a plastic pool-chair next to you can give surprising results when the bands are open...... double o three and a half... licenced to thrill. This little MFJ certainly isn't perfect (I've yet to find any antenna that is) but for allowing you to use radio in places you never thought possible it could be great fun... It reminds me a bit about my old Yaesu FT817... in spec terms the size compromises they made makes it one of the worst performance HF rigs (on paper) available but I'd never sell it as the smiles it gives me because it can be fun everywhere still make it a winner. hope this helps - Ian gm0sim (for people interested in magloops in more detail just check out the groups.io forum dedicated to them).

Depending on the diameter of the wire you could use a child’s hoopla hoop and run the wire inside of it . Then you would have something that looked nicer and you could mount it on a Tri pod

Yes you could but there would be little point. The antenna has its own built-in tuner and adding another tuner in series would make adjust confusing to say the least. 73 Peter
