Very nice for the price

I put this antenna up a few weeks ago, after resoldering all of the solder joints and where they crimped but did not solder, just in case, something MFJ is known for in the past, ( cold joints )
To be fair to MFJ I would resolder any other antenna too.
I put up three 10' fence top rails with a bolt and nut through the slip joints of the railing, they are not a tight fit but I nave used these for years with no problems and mounted a pulley up top with a PVC stand off and attached the antenna at the center feed point with nylon rope for raising and lowering. I also cut about half of the 450 ohm ladder line to fit my installation, the 100’ is not critical and can be trimmed if needed.
Now for the antenna review. I check into a 40 meter net from time to time from Coquille, Oregon with net controls in Grants Pass, OR and Reno, NV, and Shingletown, CA. They have all given me very good signal reports compared to my old home brew dipole. I get S-9 to 20 over reports from these stations and other stations that include Idaho and Utah. I am very pleased with this antenna on 80 and all other bands, Its been good from Japan to Whales. I have not set it up for 160 meters, I intend to build a 142' sloper for that. I use a Kenwood TS-2000 with a MFJ 969 tuner @ 100 watts and have no trouble tuning this antenna, my auto tuner works well too with this antenna.
Overall I like this antenna and would recommend it to anyone.

Using it for a Loop antenna
|
Time owned: 0 to 3 months

I wanted a 17 meter loop to be fed by 450 ohm ladder line. I cut the ends off this doublet, giving me two pieces of wire with insulators for a possible 20 meter dipole, and used the remaining portion of the antenna with the middle insulator and ladder line for a 17 meter loop. I ran it back across the top of my house from about 30 feet up on my tower and connected the ladder line to a MFJ-912 W9INN remote balun box. Then the rest of the way to my tuner with RG8x. The 1777 is sturdy and well made, similar to the MFJ G5RV. If not for the G5RV up there in place, I would run the doublet, instead, with a tuner.

Works OK; poor quality assembly
|
Time owned: 0 to 3 months

The wires are crimped at the ends, not soldered. While the antenna was still in my hands, while putting the rope on one of the end insulators, the crimp fell apart. I took the antenna back inside and soldered the ends around the insulators. It would have been annoying if the crimp had lasted just long enough to get the antenna up.
Works OK once the assembly flaws are corrected.

Okay for the price

No longer owned, but worth it at the time for the 450 ohm feeder alone.
Now running a Windom for 80m - 10m

Good,Cheap, Multi Bander

I took advantage of the strong pound to buy one of these antennas direct from MFJ. £50 in the emporiums in GB. & $50 direct from MFJ in USA. Even with p&p & charge for money conversion this antenna was less than £40. This antenna is same size as a g5rv, but fed with 100' of 450 ohm ladder line! (how much would 30m of 450 ohm ladder line cost?) the elements are made of good quality flex-weave. My first contact was with ZL6LH & a report of 5/9 . Just using 100w from a Kenwood TS870 & the antenna up at 40' with one end at 35' & the other end at 25' I have used a Full sized g5rv before & this antenna was like having the g5rv but with an rx amp & a tx amp coupled up as well. I took my 40m dipole down as the doublet out performed it. & it beat my carolina windom cw160s on 40m, 20m & 17m bands.
On 160m I use the antenna as a Marconi T (both elements fed at the same time & worked against ground) & it works a treat. Won't be as good as a topband dipole, but for limited space (102' top) I don't think you'll get much better. This is the 1st antenna I've taken time to review (& I've had a few!) & thought I'd best share my thoughts,as for the price, this is one multi-bander that has to be a really good compromise antenna.
If anyone needs any more details, please feel free to e-mail me m0vey@aol.com Thanks, Phil.
