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!!!

Well Built  Time owned: more than 12 months
The Cobra Sr is built well.I first put up a Cobra Sr that I pulled out of Joe,s junk box at one of our local Hamfests. Nothing was wrong with it other than old winter beaten age. I flat topped it about fourty feet up end to end with ladderline dropped down to about ten feet off the ground, then over to the shack.Home brew balun and four and a half years later still good results. 1.1/1.2 swr 160/10. Joe just sent me a brand new one with the Balun Designs 4113, and I suspect this new one will be up for the next ten years here in Maine. I have actually only bought about five antennas since 1959,Mosley,cushcrsft,and Titan's,and always have built my own.But after a few heart attacks and It was time to call Joe for one more Cobra Sr. Joe answered the phone in about two rings and that was on a friday,and Monday morning the antenna was sitting on my desk. Thanks Joe. As for the Cobra SR Joe gives you the antenna ready to fly. And it will do what it is supposed to do. Some may have to make a tweak here or there but if you don,t chop it all to hell it is one good antenna. It is easy to roll out and hang.I will still make my own but I also will call Joe for a Cobra any time I have a chance to hang one for my friends.New or old timers,Joe's Cobra will give you lots of talk time and less head scratching. Thanks

Great Antenna  Time owned: 0 to 3 months
Joe and his crew have designed a great all band antenna. I will keep this review short only to say it REALLY works well.

Great perofrmance is little space!  Time owned: 3 to 6 months
I am in a no-outside-antenna neighborhood and have tried a couple of different antennas n the attic. Prior to the cobra, it was a G5RV jr. I put a cobra jr up and it performs much, much better. I am always able to work any DX I Hear and I get great reports.

You need to run ladder line all the way into the shack and then use a tuner. With this combo, I have nothing but great reports and results. I still have the G5RV up, and will use a coax switch, there is at least 6db difference - more on some bands.

Solved my problems  Time owned: 0 to 3 months
Well, I have several challenges at my qth. The room in my yard is about 25' by 25' and very close to the station. I was running an inverted vee shortened 80m OCF dipole, and still couldnt fit it w/o doglegging one end. It worked well till I got an amp and started running some power. I was getting rf or common noise in my signal (a lot), and some electrical anomolies in the house.So an extra I know told me about using a balanced doublet, and feeding it with ladder line. I think he thought I should build it, but I dont do that, and then I saw and ad on this site for Joe's antennas. The junior fits in my yard at 32' apex, and the ends are off the ground. NO rf in my transmit! Good reports so far on all the bands ive been on including 80m! Easy to install. Very lite! I put dabs of coax seal on all the exposed connectors, and also purchased a Balun Designs balun from Joe. I want one antenna for all bands, and with the room that I have, the Junior has made my day. Hard to believe that a 71' foot antenna will do as good as this. You will need a tuner, and my LDG 600 Pro2 tunes all bands easy. $115 bucks? What a great deal!

Excellent Antenna  Time owned: more than 12 months
When I got back into Ham Radio after a 30 plus year hiatus, and I began looking for HF gear, I noticed the Cobra Jr. and saw that it had been bought by Army Special Forces. Being an old SF soldier, I figured, if it was good enough for them, it was good enough for me! I was amazed at how light it was and I can imagine that the team radionman is thrilled to have such a light antenna to carry in his ruck sack. So I put it up. I really had a lot to learn/re-learn about antennas and HF commo. Once I e-mailed the mfgr and got some tips on how to put it up right, I was amazed at its performance. I have since donated my Jr. to a college Ham club and purchased a Sr. No. It's not a miracle antenna, but if you put it up right, it will perform. I have mine up about 55 ft. in a large pine tree with the ends coming down in an inverted v. I think one of the keys to performance is to have the ladder line hang perpindicular at least 35 - 50 feet. I don't even have my residual coiled up I have a gentle angle through the trees to a 4:1 Balun and 76 ft of RG 213/U coax to a choke balun into the shack. I regularly run 100 to 500 Watts and I break through pile-ups and pretty much get whoever I can hear. Seems to work well on all bands. I use an Ameritron ATR 30 tuner - a good tuner is a must for this antenna. I've had mine up for about a year now and shortly after it was put up, because I put too much weight on the ends, the wire snapped just inches from the center insulator. It was stripped and soldered, protected with heat shrink and since then (with a slightly shortened element) it hasn't missed a beat. As for homebrewing the cobra or similar antenna, I think that the lightness and strength would be hard to duplicate. Right now it is the only antenna I use and I'm extremely satisfied with it. Customer service is great also! Well worth the money but make sure you follow the mfgr's recs. on how to put it up. I think you will be very happy with the value you get for your money.
