    I bought one and did some mods to it. I wanted to use it for my digital mode radio at no more than 75 W. Worked great. One day I noticed some stringy stuff hanging on the shed below the antenna. I realized it was the balun box that had melted. I changed the balun to a 9:1 rated for 2.5 KW, but never transmitted more than 75 W. To accommodate the lager balun, I remove the old box at the bottom and replace it with a larger box and provided screened 1 1/4" vent holes. Wow, what antenna for the money. I moved and bought a Titan Gap for my new backyard. I love my Titan, but I'd go right back to this antenna if something were to happen to the Titan. I've thought about making a with mount and using it for POTA, if I can ever get motivated. Worth the money, and the upgrade cost, in my book.

    Most chain-link fences make exceptional radial systems for vertical antennas regardless of band. The longer the better, especially on the low bands. The older fences which have horizontal pipes on top work the best. Just make sure to bond the horizontal pipes to the posts in the ground with good quality braid. I have used mobile antennas, 6BTV's, Hy-Gain's, and others, including a home-made 75/40 meter vertical. With a little tuning, all worked fantastic!

    Nice shirt! I was the Chief Engineer at WLS and the company LMA’d the Loop for a few years. Sad that it’s gone now. I have just put up the aluminum version of that antenna with an auto-tuner at the base, and I have radials under it. No vertical will work well without radials. Anyone who believes that doesn’t understand the basics of antennas. Just because you have good SWR doesn’t mean it’s actually radiating a good signal. Even a dummy load radiates to some degree, but you won’t be working many people on it. I can’t speak for this add-on radials, but mine are buried in my yard.

    I had the MFJ version of this antenna. It worked semi ok on 20 meters and above. I might have made a contact or two on 30 meters. It was basically useless on 40 and 80 meters. It was, however, not a bad antenna for shortwave listening. After about one year, the mount failed from metal fatigue and the whole thing came down in a windstorm. You can save yourself a pile of money and put up a simple random wire made out of speaker wire and get much better performance to boot.

    Hey Walt! I have the Sigma, aluminum version of this and use it as a portable antenna for my motorhome. I utilize a couple of different mounting options - ground mounted on a bicycle repair stand that I have modified to bolt the bracket on and a flag pole mount on the rear of my coach that gets it about 14' up in the air at the base. I have had outstanding luck with it as I travel around the western US. I've worked all over North & South America, Asia, the South Pacific and even a couple of openings into Europe. I regularly check into an 75m net in the evenings as well. All of this barefoot on a IC-7300 or my old Yaesu FT-100 mobile, all band rig. While on the road in the coach, I don't have the luxury of a fixed antenna. This gives me the ability to get on the air, have some fun and provides a quick and easy way to deploy an antenna, even in a limited space like a campsite! (I also carry two 9:1, EFRW - 1 50' and 1 84' as well as a ZSKBKW dipole with a 40'' extendable fiberglass pole in the MH for those times when I have more room to play with)

The only thing that I had to do was waterproof the joints and drill a couple of holes on the underside of the unun. Furthest contact so far from the UK is Uruguay, 6,735 miles!

    When people take advertising, nearly *any* advertising as being 100% truthful, I think they're usually going to be sorely disappointed. I first learned that lesson when I bought some "Sea Monkeys" from an advertisement in some magazine when I was a kid. I didn't get any "monkeys" at all, "sea" or land-based. The only thing I got were some tiny, almost microscopic brine shrimp! *LOL*
    I also learned my lesson in 1989 when I had first gotten my Novice Amateur License. I bought one of the _magical verticals_ that (supposedly) covered 80 - 10 meters with "no tuning." All I got were more "Sea Monkeys," just in a vertical configuration. 😆 Actually, that antenna did have radials included, and probably worked better that many of the other multi-band verticals that were/are sold.

I check in to the 80 M and 40 m Regional Nets with great success. While it is not an excellent 80 M or 40 m antenna, I have found it works really well for regional check-ins on those bands.

Longest contacts for me using that antenna and those bands was 10 meters to Australia and New Zealand countless times along with Johannesburg, South Africa on 17 meters during 2009 solar minimum along with South America, Russia, Europe, etc. It was best 65 dollars I spent at the time back in 1999 and its still up 24 years later and still works. I might even buy another one at some point to replace the current one.

I removed the unun, from the bottom, took the connector off and and reinstalled it on the bottom of the antenna. there is a hole already drilled and the connector fits perfect. I also added 6 radials to this setup have it mounted on the roof sitting in a cement weighted patio umbrella stand. I have used it on 15 as well with good results but 10,12 and 17 it does the job well with my setup.

    Hi Walt, it’s a good review.
    If you can live only with 20 meters, a delta loop antenna can also do wonders. It has low noise floor and its gain is better than a vertical, it’s not hard to build one with wire and a 4:1 unun.

    I just don't see it as a bargain or great antenna. Granted it's a simple install and does not take a lot of space: However, if I am going to need a tuner and another easy to install antenna I have great success using a 9:1 unun with a 41' radiator wire and 25' counterpoise. The end of the radiator wire can be hoisted over a branch or tethered to a lightweight fiberglass mast with total cost under $100.

      Ironically most guys miss that an aluminum mast itself can be used as an antenna provided you use the correct length for the frequencies. Its even broader on band because b of its size of 1.5 to 2.5 inches. Radials in still required

Just curious if you have tried this. If not, no worries. I will put a meter on it and let you know where it is resonant but since it doesn't (appear) to have any "coil" section Im thinking it may be perfect for 10 meters. Will keep you posted!

Interesting thing is, the paper that came with the antenna said that auto tuners will work fine on the harmonically related bands (80-40-20-15-10m) but a manual tuner is required for the WARC bands. I found out this is not so, the great tuner in the G90 works fine on all the bands. Great deal for about $150 (with shipping from UK)

    Never buy the x80 aluminum version unless you pot the un-un or better still move it from underneath and seal it in a box (I use a sandwich box). The fibreglass version is not a problem. The extra radials plus pack really does open up 40 and 80 once you have tuned them (the whips can also be used portable like a hamstick) although they are best described as fair not good. I lasted six months with one of these before setting up a long wire as well but still use the x80 which together with a mag loop and the long wire gives me all the QRP performance I need in my small shack . If you are just starting up or even a CB'er then give it a go - it really works. 73 . M7BLC

    I’ve seen this and similar antennas, and wondered how (or *IF)* they could work. I’ll have to check out those specs. It almost sounds like a *SHORT* vertical *random wire* - perhaps with a 9:1 UNUN attached?
    That said, I wonder if you could say it’s the _”best”_ antenna for its size, form factor, and cost? IOW, *ALL 3.* I’m sure a simple dipole would work better and be cheaper, but the form factor would be much larger. I’m guessing that it would be more efficient than hamsticks, shortish coil antennas, etc.
    For my needs, I would *START* with the size constraints, then figure out how to most efficiently use that length. I would *GUESS* that you could design a *trap vertical* for 6-20 meters, then figure out a way to tune 30-80 on it. I remember a very old adage - _”if you want more signal, you gotta stick up more metal”._ 😀
    P.S. It’s now $105 on Amazon.
    P.P.S. I looked at a couple of the _”random wire”_ websites, and the lowest number I could find was *_29 feet._*

    I bought one and have mounted it on a 10' pole. At this height off the ground the best SWR I can get is 4:1. I'll have to lower it get the SWR right. But worse, it doesn't hear very well. Even if I get the SWR right I will go back to my MFJ-2220 because of the reception. I'll play with it for a While.

    Regarding 10m performance not sure why you experienced poor results….as a half wave end fed vertical it should perform even better than on 20m as a mere 1/4 wave.?…maybe it needs a different ratio un-un…should not need any ATU with the correct ratio.

    I wish I had seen this video before I bought the Sigma Eurocomm version with the 40/80 radial kit. In practice this antenna is a complete waste of space, time and money. It halves my signal and introduces noise where noise on my end fed wire has none. I have the fibreglass version and have tried it on a metal roof, at ground level and on a 7 meter pole. Nothing, nada. It’s not really that good on 20m in any case but on other bands it’s useless.
    The sick thing is the “branded” version sells for something like US$500 here, I got mine from the UK and it was still not cheap. And it started to rust within days of installation even though I’m a good distance from the sea.
    Save your money, it’s junk. Great review.

    Hey, great vid. I purchased this same antenna and put it up on a mast on my roof. Its up there pretty far. Since I cant ground it (radials) I've started making my own counterpoise for it on the 20 meter band (1/8 wave and doubling up) . Made a DX contact yesterday all the way to hungary and I live in the Midwest with trees all around (running 10 watts btw). I'm still playing around with it though. Im mounting the counterpoise wires to the "U" bracket that attaches the antenna to a mast. What are you thoughts on this approach? Do you think there is a better location to mount these counterpoise wires? Thanks!

If you're looking for a multiband antenna and have limited space and options this is a good choice as long as you have a way to tune it with either a built in Automatic Antenna Tuner in your radio or an external one.

It will cover the entire 10 meter band! I wasn't able to connect it to my radio but my analyzer shows a 1.4:1 SWR across the entire band. By the way the 98" is from the very bottom (of the threads) to the top of the whip.

      From what I’ve learned the coil antenna when tuned properly is a resonant antenna and will have less loss than an antenna with a transformer. For the small shorter size it’s a great antenna but probably doesn’t perform as good as the long vertical half wave antenna.

    Hi Walt - Based on your initial review, I purchased a HF 360 from Sigma. The tip of the whip is at 24'. I do not have any radials and it works okay. FT8 contact in Mexico was about as far as I've gotten. SSB as far as California, but mostly closer to QTH. On average I see that 1000 - 1500 miles.
    I am assuming the metal roof/flashing whatever it at your home/condo was acting as a ground plane in your first video. Unfortunately I have no way to run radials; perhaps I could add some rigid radials, but I would need to figure out if that would be helpful and if so, what length and how many.
    Your audio was not the best ever... I will have to watch again with headphones on.

      Your radials should be 1\4 wave to desired frequency of the antenna. 3 or 4 it's great. If you want it to be more directional have them form a V open to the long path for DX. 4' above ground is good but a full wave or half wave is perfect.
