Solid performer for what its designed to do  Time owned: 0 to 3 months
I have a 4 band OCF Dipole that I've been using for a year or so and was looking for something else that could do multi band but better performance than a G5RV and this is what I decided on. I am pleased with my purchase after using it for a few days all over the bands from 80-10 on SSB and digital modes. I use an LDG AT100 Pro 2 tuner and switch back and forth between the OCF and the Cobra and notice about 1 S unit better on the recieve and the transmit I can go back and forth and the reports seem to be about the same on the other end. I am able to tune up no problem from 80-6 meters and easily get less than 1.5:1 match. In my unscientific "seat of the pants" feel for this antenna has been good. I only give it a 4 because the ladderline is a pain to deal with. I'm going to try switching to 300ohm twin which will be easier but hopefully doesnt degrade performance.

Really disappointed  Time owned: 3 to 6 months
I ordered the Cobra Junior Lite several months ago after e-mailing them to ask if putting it up as a semi-vee would make a difference in performance and receiving no firm answer. I bought it anyway and friends helped me put it up on a fiber glass pole at 33 feet the legs 31 feet apart and 10 feet high. The man on top forgot to wrap or loosely coil the ladder line around the mast for 26 feet.

I contacted COBRA and asked how to make up for that error. After discussing where the other 50+ feet were I never received a answer on how to improve it with this error. In fact I never received a contact of any kind after the 1st one.

With no customer support I must say this antenna is a dismal performer and I don't get half the contacts I got on the antenna I was using before this one. I cannot recommend this antenna because of poor installation instructions, lousy customer support, and I just can't get it to work right. Contacts that I used to make easy and regular I cannot even raise now. I believe this antenna, its instructions, and customer support are the worse I've experienced with any HAM equipment. I know there are others who rate this highly but I cannot . I just learned another expensive lesson, maybe I can save you from the same fate. I wish I had my Alpha Delta DX-D back it worked really well.

Treat It Like a Vertical  Time owned: more than 12 months
Simple trick if you have RF in the shack when using this antenna. Used it as a dipole for more than a year and something got me to try it on 40 meters which went fine at low power but > 100 watts monitors would flicker, AM/FM radio would buzz - lots of RFI. So I put out a quarter wave ground wire on the
coax side of the 4:1 balun. Problem solved. But it seems now schematically that is 2 inverted Ls fed in phase against the counterpoise. If the snow ever melts here in NH, I hope to try more radials. Also want to see if radiation efficiency is going up as the radials are added.

GREAT COMPROMISED ANTENNA  Time owned: more than 12 months

Worth It  Time owned: 0 to 3 months
I just hung an UltrLite Jr as a sloper, about 60 feet in a pine tree on one end sloping to about 10 feet on low end. Ladder line floats over top of foilage in the forest preserve behing my home (live in HOA restricted area), to a 4113 Balun Joe sells, with the excess ladder line loosely coiled. Coax is run to the shack about 100 feet away. Very quite and great signals. Tunes easily except on 80 meters, 75 meters tunes pretty well however. I highly reccommend it and seriously considering another one for mobility like field days, etc.

K1JEK Folded #1 favorite!  Time owned: more than 12 months
The ratings here go from 0 to 5. Too bad they don't go from 0 to 6...because this is truly a better than great dipole. In my over 35 years of enjoying our fine hobby, I've found that this is the best antenna I've personally experienced. Some caveats: Don't set up your station on the second floor; your basement is best. Second, suspend your antenna in a loose fashion. Third, get a big beefy external impedance match. Fourth, use a good current balun, like the DX Engineering models. And 5th, have fun. Remember there is no perfect antenna but this may be just right for you. I've had a lot of fun with mine, and hope you do too.

Excellent to deploy with  Time owned: more than 12 months
It is durable. We use it in a NVIS configuration for the Texas State Guard when deploying to emergencies. Fifty foot mast and a couple of fifteen foot poles and we're handling traffic.

Generally, we can set up a ICOM 7200 with auto-tuner on a folding table with a laptop for digital messages in less than thirty minutes. The Cobra Senior is chiefly why we can start operating so quickly.

Great  Time owned: more than 12 months
I've used the Cobra for about a year and couldn't be happier. I've got it up about 30 feet, with a short segment of ladder line into a 4:1 balun and then coax to the rig. It does need a transmatch, and my little MFJ-971 gets it down to 1:1 on 40 and higher. 80 is harder to tune, but I can get 1:2, which is serviceable. It has gotten good signal reports and allows me to hear well on 40 and 20 even at times when my R8 is noisy by comparison. You do need to get this antenna off the ground and if roof mounted (like mine) at least 10 feet off the roof. I originally had mine 4 feet off the roof edge attached to a pole on the chimney, but it worked a heck of a lot better when I raised it another 6 feet.

outstanding  Time owned: 3 to 6 months
I have just retired and about 5 months ago purchased my little retirement bungalow in the Pocono mountains. Well, I had up a TA33 jr, and a home brew 12/17 meter Yagi. I thought I had a pretty good station. Needless to say, at my new home I did not have a tower, so could not put up anything to get on the air with. I checked on the Cobra antenna, and finding nothing but good reviews, decided to purchase the 80 thru 10 version. A couple of fellow hams helped me get a few lines up in the tree's at about 70 feet which put the antenna at about 60 feet. I can not believe the performance of this antenna. Easy to tune with my Palstar AT2K, and loads up beautifully with my AL572 linear. Without the linear, receive and transmit is terrific, and tunes easily on all bands. This has fit my needs and then some to the point, I am considering not putting up my beams!
I highly recommend this antenna in all ways. No trimming required, light, does not need a center support, and WORKS LIKE A CHAMP.

Just installed....a Cobra JR.  Time owned: 0 to 3 months
I'd been having "issues" with other dipole antennas. Was talking with a friend, and he suggested the Cobra antenna. Decide on space requirements and order accordingly. Due to lot restrictions, etc., I ordered the Cobra Jr....put it up last night....and WOW! What a major difference! Fired up this morning and spoke with someone in AZ...with NO problems! Well...trying to set up a "go kit"...guess I'll order the CObra Sr. for it! VERY VERY pleased with the money spent!!!
