MFJ-1729 Review  Time owned: 0 to 3 months
I was really hesitant to buy another MFJ product because I had purchased so many MFJ products in the past that were defective because of poor quality control. The reviews sounded so good that I decided to take another chance and buy one. When I opened up the package I noticed that the rubber protective piece that was on the bottom of the mag mount was deformed and was coming loose! This was very upsetting so I called HRO and explained to them that I had a received another defective product from MFJ. They were very nice and told me that I could return the defective MFJ antenna and that they would send me another replacement. After seriously thinking about all of the defective MFJ products that I had received in the past I finally came to the conclusion that it would be better to ask for a refund and spend a little more and buy a much better quality built antenna from a different manufacturer. Very dissatisfied!

MFJ can make a good product  Time owned: 0 to 3 months
Reading most reveiws about MFJ, one would think that anything that comes out of Starksville , Miss would be pure junk. That is pure BS.

Bought this antenna from HRO and it arrived in a super nice and HUGE box to protect it ( thanks HRO ) Very nice packaging if one was looking at it on a display board. I coated the plastic ( rubber?) base and O-ring seal ( goes around the screw on fitting for ant,)with 3M Silicone paste to protect it and also about 1 foot of the coax from the base to also protect that from the elements\UV.

VERY strong magnet that did not move at all and my car gets up to 90 MPH at times on isolated roads. T

The whip did not flutter or sway in driving and I like that. Fairly flat SWR ( 1.3-1.5 ) on 2-meters . THe addition of BNC adapter is just great as the primary use for this antenna is with my trusty Radio Shack HTX-202 HT , battery powered . I noticed that I could immediately HEAR stations that I could not before. Hit the Blumont, VA repeater, while 50 miles away near Frederick , MD on 5 watts or less from the HT. A real improvement that was a pleasant surprise.

MFJ does have quality control issue's but they're American made and affordable.

I'd recommend the antenna, spray\apply rubber parts with either 3M Silione Paste or good ole' Amour All to protect against UV .

Why pay more?

Whistles!  Time owned: 0 to 3 months
Bought the antenna and mounted it on the roof of my 4 door pickup. Driving down the road I noticed that at 40 mph and above there was a very high pitched noise coming from the area of the antenna. It was really annoying. Tried changing the position but nothing helped. Finally tried wrapping the coil section in electrical tape. Voila! Problem solved. Had to drop a point for this.

Oh, it's a great antenna I was able to hit repeaters from 90 miles away with a HT in the truck. Really impressive performance.

I'll update as I have more time with it. I would recommend it, especially for the cost. But be aware it might whistle for you too.

Works Well But....  Time owned: more than 12 months
The MfJ-1729 works well but be careful of the center pin on the PL-259. When parking my car in NYC I remove my radio and antenna. Taking the antenna on and off from the back of the radio is difficult and eventually the center pin weakens.

solid, great performance  Time owned: more than 12 months
Had this on my car for almost 4 years now. SWR is 1.1 to 1.3 for 2m and around 1.5 to 1.6 for 440. Has held up really well, never comes off unless I want it to. Where my trunk lid has opened and closed on the wire over and over it's worn a hole through the plastic and the inner coax mesh, but it's had no effect on performance. Probably will have this antenna forever.

Does really well  Time owned: 3 to 6 months
I purchased this antenna to replace one of the so-called better antenna companies dual band antennas. My receiver was way better than before, and I was getting into, and staying into repeaters, that I once could not hold. I highly recommend this mobile antenna.

Decent Antenna  Time owned: 0 to 3 months
A decent and very affordable antenna. It is very flexible, which is a plus for me since it gets whacked regularly by a low parking garage roof.

Performance is equal to more expensive Comet and Diamond dual band mobile antennas with equivalent gain figures. Time will tell how durable it proves to be.

Good antenna, needs more bandwidth  Time owned: 6 to 12 months
This is a good antenna overall, but the bandwidth near the band edges of both 70cm and 2m leaves much to be desired - the SWR at these points is 2.5 to 1 at least. Adding a long counterpoise wire wrapped around the magmount connecter helps a lot, but you'll need to experiment to tune it to the frequencies you want. Also, the PL-259 connector seems poorly made - I often need to jiggle it around in my radio to make the antenna work. However, when this antenna works, it works great! The magnet mount seems quite strong, and the antenna radiator seems sturdy and well-built.

Overall, this antenna seems good, but has enough detracting from it that I am forced to only give it a 3 out of 5 rating.

Very happy  Time owned: 0 to 3 months
I just got this antenna about two weeks ago. I bought it so my MFJ1724 could be used for my APRS radio in the car. This MFJ1729 is doing a great job of bringing in the stations. Since moving to this antenna, stations that were S3-5 are now S7-9. Is is taller then the MFJ1729 but is more flexible so it fits in the parking structure at work.
Feel free to email me if you have questions on this antenna.

OK. Mostly  Time owned: more than 12 months
This antenna is fantastic when its 100%. I used my 1729 for about a year and it was awesome. Had QSOs up to 140mi away with 6 watts power on an HT. No problem until the connectors/coax broke.

The connectors/coax/something crapped out 14 mos after I bought it. For the cost of a new one, it's not worth a lot of time trying to figure out what went wrong and try to fix it. I'm just outside MFJ's 1 year "no matter what" warranty.
