9 Years Later Time Owned: more than 12 months.
I originally reviewed my Scorpion 8 Element 2M Quad in 2002. I just performed some maintenance on the antenna. The antenna was in great shape. The boom was shedding a little fiberglass. I gave the boom a nice black paint job, and back up on the roof it sits. I have changed polarity to horizontal, and use this antenna in all major VHF contests. Works great. If you go to my QRZ.com home page, you can see it up on the top of my roof. Highly recommended.

Excellent deal Time Owned: more than 12 months.
After > 10 years my quad needed some extra fixtures and Roger volunteered to send them in. His support is important as hardware sold in some stores as stainless rusts in a few months. On the other hand, his hardware is time proven. I am happy with my quad. It has monoband gain, is relatively light, and it can be fixed in no time. It is on a roof tower. This way the bottom can easily be accessed for tuning while the center of radiation is higher.

Follow Up Time Owned: more than 12 months.
This is a follow up to let hams on the fence know how the antenna is performing after one of the worst winters here in the Northeast. I live upstate NY outside NY City and we had a horrible winter this year with plenty of ice storms as well. Well, I am please to report I had not one issue with the antenna at all. I had quite a few scary situations with ice buildup and strong winds and I held my breath and to my surprise there wasn't one moment that I was unable to use my antenna.

I was told by quite a few hams that my antenna would come down in ice and strong winds but this was certainly not the case. I hate to jinx myself but I attribute the success to the quality of materials and construction Roger @ Cubex uses with his antennas. I would never hesitate to buy another one if some unfortunate incident were to occur. If you want a big signal and quite antenna buy a Cubical Quad.

10 Meter Expo-Pleasant Memories Time Owned: more than 12 months.
Hastily purchased when I moved out here in 2000 with so much to do and so little time to build antennas. It went together in a few hours and was lashed to half of a rusty old tower left here with a TV rotor.
I have no test equipment to confirm or dispute its performance claims, but I know that many many European and Asian contacts were made--50 watts--and many more at 5.
It was placed behind my barn, then became a victim of my carelessness. So a new boom and a couple spreaders will be ordered this week.
Great little antenna!

Great Performer Time Owned: 0 to 3 months.
My 2 element HF Cubex Quad is up in the air at 10 metres and performs very well. It's about 3 S-points better than my multiband ground plane and is very quiet on receive. It seems that if you can hear it on the Quad you can usually work it. It gets through very well and anyone considering building one wont be disappointed as the materials supplied are of a high order and the performance is excellent.

Excellent antenna Time Owned: more than 12 months.
I installed the 4 element 10-15-20 antenna and have been very impressed with the signal reports and its performance. It has been up one year and survived an ice storm. I got good support from the manufacturer for the few questions I had.\W8VZ

Love my Scorpion 88!!! Time Owned: more than 12 months.
Fantastic antenna. Easy to assemble, fantastic performance, outstanding F/B and side rejection. The only way I could be happier would be to stack them and put them up higher.

Cubex Quality Time Owned: more than 12 months.
I have a 3 element, 4 band Cubex Quad that just went through a Category 5 Cyclone. The Quad survived without a problem but the tower sustained some damage from a large branch from an Iron Bark tree.
Wind gusts were reportedly in excess of 280 kilometres an hour, I had 9 large trees ripped out of the ground and numerous small trees either laid over or ripped out and blown away.
The elements are direct fed except for 10M which uses a 3/4 wave 75Ohm coax. No baluns or gamma matches, all bands are less than 1.5:1 where I need it to be. (12M wires are not installed)
The antenna is over one year old and previously I had a Cubex 2 element, 5 Band Quad and it worked flawlessly.
Well done Norman, you build the best Quads around.
Oh, and before I forget, it will soon have a fourth element added.

Small size - Big performance! Time Owned: 3 to 6 months.
I use the Magnum 2CB (two element mono band) quad due to space limitations, however the performance is unbelievable for such a relatively small antenna. It's mounted at about forty feet & fed with Ecoflex 10 (another great product)& it drastically reduces static and other noise compared to a three element Yagi. Performance is claimed to be 7dbd gain, we'll all I can say is that I'm getting out further and pulling-in better (with less unwanted noise)than I ever did with a Yagi. Build quality seems to very robust although it's yet to survive a North East winter! Assembly was simple and SWR was acceptable for a pre-tuned element (I calculated my own eventually)The Cubex customer service are efficient & helpful. Oh, & Norm is a top geezer too - when do I get the extra 10% discount Norm??? Hi Hi, 73's

Great (with a little help)! Time Owned: more than 12 months.
I purchased the Cubex Mk II 3-band (20-15-10) 2-element quad on an 8-foot boom in 1996, the second time I had built this antenna. Based on 10 years of experience with the earlier quad in a very windy environment (western Washington), I knew exactly what I needed to do, to make it permanent. First, to eliminate "boom sag" with the earlier quad, I substituted 1/4" thick aluminum for the supplied 1/8" thick aluminum. Second, I threw out the "pre-tuned" solid wire elements (no quad can really be "pre-tuned," if you really want best results), and substituted #14 stranded copper with tough THHN insulation. Third, I attached the elements to the fiberglass spreaders with a combination of UV-protected tyrap plastic and a short run of insulated wire. Finally, I tuned each band separately on the 40' tower for best F/B at the design frequency. The "reinforced" quad has survided winds close to 100 mph on occasions, with no damage over the past 8 years. The Cubex quads are probably the best on the commercial market, but if you really want to make them survive permanently (and continue to irritate Yagi owners!), you can make them a little better, like I did.
