Worthless Mechanical Construction  Time owned: 6 to 12 months
Had it up a little less than a year now on an 80/40 fan dipole. It handles 1200 watts but I usually run less.

I bought it for the price and noted someone said it had fittings threaded into PVC. I ordered it and planned to send it back were that the case... I checked and it is threaded into metal. Great! Well, for not quite a year. The threads failed from the weight of the wires. I dropped the mast and pulled it all together with black nylon ties so it still lives.

Probably OK for higher frequencies and lighter wind loads.

Good Electrically, Mechanical Failure!  Time owned: 3 to 6 months
Works fine Electrically, leads out are better than making connection via Eyebolts like Unidilla , but the Eyebolts are only threaded into the PVC Pipe and strip out under any significant tension , had to make my own Center Strain Relief .

Perfect  Time owned: more than 12 months
Does exactly what it is supposed to. I have subjected it to legal limit power for around 2 years with no problems

Junk -- Don't waste ur money  Time owned: 3 to 6 months
Worked fine to start with on a homebrew 20/17/10 fan inv-V dipole 35' up, then 5 weeks later, it crapped the bed. Still works as a RX antenna, but can't tune for TX. Tried calling both MFJ and HamCity (whom sub contracted to for this), and it is impossible to get a live human there. Thankfully, is giving me a full refund for this POG. Please don't waste your money on this, and do not give either MFJ or HamCity your business.

Great Product  Time owned: 6 to 12 months
I use this to center feed my 40/80 meter inverted v dipole on top of a 50' mast. Does the job at a good price. I have no issues with RF in the shack or SWR. Handles the 1kW my amplifier puts out with no issues. The eye bolts are strong and support the wire element tension securely. It's been up for about a year now with no complaints.

Junk  Time owned: 0 to 3 months
I got the balun about a year ago but just start the project last week. First trip on the 259b and there was problems.
So I removed the balun, problem gone. So I tested with a multi meter and it showed a direct short. I took it apart and when it was assembled they had twisted the 2 copper wires around each other before they exit the housing. Another check and now an open short, so off came the bottom portion of the balun. The braided portion of the cable was not soldered onto the so239. It look like there was solder there but not connected. Soldered back up, reassembled and now its good to go.

Good balun for the price  Time owned: more than 12 months
I have had this balun in service for about a year now. We have had some really heavy rains during that time and I have not had any issues with water in the balun. Antenna's tune and work fine. I will be purchasing more of these to have a few extra's on hand.

Good for the price  Time owned: 0 to 3 months
I bought 2 of these, one of which I tested on my portable 17-meter inverted vee. The thing tuned to a perfect 1:1 SWR, so I am very pleased about that. Also, the balun is built like a tank (and as a result is quite heavy).

I have one gripe about my unit, which is the reason I gave it a 4 instead of a 5. When it arrived, all three of the lug bolts were somewhat loose, so I had to tighten each one of them. Yet another example of far too many products today that have to be fixed by the purchaser before they are even put into service.

Overall I'd have to say, though, that it's hard to beat for the price.

Does the Job  Time owned: 0 to 3 months
Just installed yesterday, it did stabilize my 80M inverted V and takes 1KW with no problems. I am a little concerned about liquid intrusion and there is no drainage hole so I tried to drill a small hole in the bottom for drainage but hit a metal plate after the PVC and chickened out. I put some Pvc sealer on the mount post and base of the stress posts and after a solid day of rain today the SWR stayed put.
