MFJ1984MP EndFed 1/2 Wave 300W 40M-10M Wire Antenna

Absolutely spectacular. Easy to find an eye hook or something and mount up on the side of the house. Easy to run the wire to nearby trees in an "L" shaped formation. Voice SSB range is about 1,000 miles and CW range is over 5,000 miles. Easy installation, easy running the wire, easy grounding, everything about this antenna is amazing. Works well on the 40-10 meter bands, but does not support anything else. Can't complain for about 66 feet of wire 20 feet in the air.

I installed this antenna yesterday, and was comparing it to the Hustler 4BTV I had been using. This EFHW seems to hear much better on 20 and 40 metres than the Hustler. I have already worked Japan on 20 M QRP. I did have to adjust the length, removing about 1 metre, and now the SWR with no tuner is less than 2:1 on all bands! If you have room for a 20 metre long wire, I highly recommend this antenna. NL7GW

Let me begin with two caveats. I took the statements "You may not even need an antenna tuner" with a large grain of salt. The second caveat is that I was not inclined to begin cutting an inch off at a time until I hit some magic compromise. Instead, I installed it with a 15 foot coax feeding the enclosed matching unit mounted on the eave of my house. I ran the long wire through a substantial fork in a large tree in my back yard about 30 ft AGL and anchored the other end with paracord and a soft screen door spring to the fence. I grounded the whole thing to a 24 inch steel stake driven into the ground directly below the matching unit. Running straight in to my Icom 718, the antenna gave me 1.5:1 or a little better on the lower end of 40 meters and no higher than 2 at the upper. 20 meters was 3 or so. Everything else up through 10 was in the 3 to 3.5 range. I then ran it through a vintage MFJ-941 D tuner. 40 will tune flat across the band. 20 tunes in the 1.2 to 1.5 range. 17 will tune flat across the band. 10 will tune flat across the band. I live almost square in the middle of the U.S. and have gotten good signal reports from the East coast from the NYC area to Florida and an equally good report from the northwest corner of Montana on the Canadian border. Time will tell as I work with it further and band conditions improve. But, it has pretty well performed as I expected it to. It's not magic but if you work with it it will get you heard.08/01/19 Update:The antenna worked very well until a few months ago. It covered the East Coast from my home QTH in Oklahoma well and I got pretty good signal reports. Then, the radiator wire broke twice. Repaired it both times. The second time, I moved the antenna about 10 ft to the north and a few feet higher. The whole radiation pattern changed. Now, I don't hear the East Coast nearly as well BUT I'm covering West Coast states I had a hard time with before and have gotten a few hard to believe good signal reports from places like Europe, Hawaii and Panama. Bottom line, the antenna is quirky. Even small changes in location and angle can make huge differences in your coverage. But, having said that, I have another on order to install in exactly the same place I had the first one originally and plan to use them both.11/7/20 updateI have moved to a new home. When we moved I went with new antennas for both VHF/UHF and HF. BUT, I also reinstalled my old faithful 1984 MP. It is now set as sloper from the fed end up to about 25 ft agl at a 90 degree angle to the long off center fed dipole I also installed. It works like a champ, tunes up flat from 40 - 10 with no tuner needed on 40. On received signals it is about one S point below the 130 ft dipole but much quieter. I've gotten good signal reports from both coasts and it remains very useful. This was money well invested.

When the MFJ-1984MP arrived at my house I was excited to try it out. I strung it up on a tree in the front yard to give it a go. I tuned the radio to 20m, checked my SWR and it was through the roof. I check on 40m, and SWR is still way high. Oddly enough, on 10m it started to show a lower SWR reading, but it was erratic (it would change from one reading to the next).I borrowed an antenna analyzer to see what a sweep across multiple bands would show. It stayed near infinity until around the 12m band where it would slowly start to fall until the meter maxed out at 29.999Mhz.I did some troubleshooting and found that the internal connector from the wire wound around the ferrite core met with the antenna wire was corroded. I cleaned up that connector until it shined better than new money, reassembled it, and voila, it worked as it should. SWR was below 2:1 just as it should be at multiple bands.I went with three stars because it was tough to rate. On one hand, I wanted to give it one star because it was DOA and I had to fix it myself. On the other, I would give it five stars because it works great now that I've repaired it. So I went for the middle ground with this one.

Works great - all bands and right out of the box!

It works well with my Yaesu 991a on 20. 40and 80 from my deck to a tree after a bit of shortening.

Great antenna for inside usage. I placed it in my attic, and hook it to my Yaesu FTDX 1200 and Palstar tuner... got great SWR results across the bands. Good Value.

This product was easy to run out and feed into a tall tree on my property. The minus is the feed point that I found to be difficult to anchor. In my opinion the point where the cable SO connector is located is too close to the mounting hole one would use to secure the feed box. It appears that this antenna was meant to be anchored at both ends by rope or other line.
