Impressive for MFJ  Time owned: 6 to 12 months
I can't say too much bad about this antenna. The wife gave it to me for my birthday last year in July, I put the put about 44 feet in the center from a 5 outrigged arm on my tower, tied each leg off to a tree (not my favorite spot, but what I have), and anchored the ladder line and coax at the SO239 connector.

I like in Newfoundland, Canada where it's always windy. Looking at the construction of the antenna everything seemed just OK in my opinion, and I figured it would have been blown down in the first wind storm. NOT so... it actually stood up quite well and stayed up for about 4 months. Finally we had 100mph winds one evening and the 2 legs succumbed to the trees rocking back and forth until they snapped. Good thing was where it snapped, was too easy to re-twist the wires back in place and attach with a couple small split bolts.

The functionality was great. I worked over 100 countries on it and got my DXCC in just 4 months and worked 49 states in that time also. What can I say, it works really well.

I have since built one with WA1FFL Laderlocks that is more suitable to the contiditons here on the island, however I have my MFJ G5RV with my go bag and use it all the time out in the field.

For the price you really can't go wrong.

Perfect and Durable  Time owned: more than 12 months
Had the antenna up for over 10 years without any problem. Then gave it to a friend where it does a perfect service now. It is not important what you feel but what the antenna is. This MFJ antenna works very fine and is resonable priced.

I may have gotten a bad one  Time owned: months
For performance, I would say it stacks up against any G5RV. Anyone familiar with them knows there are pros and cons. I like a G5RV in certain situations. However, I gave this one a 3 because I feel like it is cheaply constructed. I have owned 3 G5RVs. One from Antennas and More, which lasted 10 years. The one I own now from Radio Oasis, which is a very, very solid antenna. The MFJ one isn't really held together very well. With the center supported, it broke where the wire attaches to the center section during the first mild thunderstom. Moderate wind snapped it like it was nothing. I won't buy another after seeing how flimsy the construction is.

Not bad  Time owned: 6 to 12 months
Normal antenna. Erected it as Inverted Vee at fiberglass mast. Nothing extraordinary, just cheap way to be active at almost any (apart from 160 m) HF band. Unfortunately the noise level in my house is much too high. Around S9 at 80-meter-band, and S6 at 40 and 20. Combination of MFJ-1788 G5RV and mini-whip RX antenna by PA0RDT helps me to have QSOs with weak stations at these bands. Luckily bands from 17 to 10 meters are noiseless. A multiband vertical antenna would be much more noisy in my conditions, and more expensive as well.

The best multibander there is.  Time owned: more than 12 months
I have this antenna up in the trees at 18m and fully horizontal. It works great on anything between 80m to 6m, but requires a good tuner.
It even works on 160m if you turn it into a Marconi-top-loaded. I have it up for 1.5 years and yet have to meet anything better that is not a beam.
Have no problems working the entire world with just 50W(average).

And the price is unbeatable, just 50 euro's.

Two remarks:

1) You MUST use a good choke else it won't work and the neighbours will want to kill you.
2) What ever you do, do not tie the twin-line against a pole or put it on the ground, it must stay clear of any objects and run as much straight down as you can.

Extremely versatile for the money!  Time owned: 0 to 3 months
I bought this as a temporary antenna for HF and the plan was to string this up about 25' in the trees in a flat top design while I built a hex beam...

This antenna works great with my TS-440SAT. The auto tuner dials in the SWR great on all bands 80m-10m. I have gotten good contacts and distance with this antenna on 80m, 40m, and 20m I haven't really tried any of the other bands but will update this in the future if I do.

This is a great antenna for getting started affordably in HF if you have the room to mount it.

I will be putting it up at 48' on my tower in the next few days once we raise the tower and it will stay in the flat top design I think. I will update regarding the performance at that height after a little while.

Good Antenna  Time owned: more than 12 months
Bought this when I first started out and it is still hanging,(2 Years). It survived the worst Chicago winter, complete with ice storms. Worked a lot of DX with a tuner of course. Will tune 10 - 80. I still use it every day. For $39.00, its great bang for the buck.

After a year or more  Time owned: more than 12 months
Rating Great only because of the antenna material durability. Initially, I had the center up about 35 or so feet, tried running it northwest by southeast and north by south. N/S was harder to do as few end supports, anyhow... I raised it to top of tower at 52 feet as inverted vee and it worked much better on 40 meters and up. About the same on 80 meters. BUT - I decided to cut the coax -- I ran 450 ohm windowed ladder line back to the shack splicing in extra 450 with last 15 feet of rg8x and 4:1 balun. Turned the G5RV into a 102 foot all band doublet and it works soooo much better. On 20 meters, I don't even need a tuner. Of course, this also has something to do with the length of the 450 ohm stuff. Some one else's situation and set up will differ. If you are looking for a well-made antenna, get this G5RV. But now as an all bander, it works much better. Good material and parts, for the price. Try making your own from store bought material - center section, the ladder line, the wire, the end insulators .. It might cost more. ,, and,, I can see this antenna being a good starter plus throwing it up in trees temporarily.

good performer  Time owned: 0 to 3 months
I have been using a 200ft homemade loop at 30ft for about a year and have been pleased. I installed the g5rv at 30ft a few weeks ago. In my side by side comparison, the g5rv outperforms the loop on 12, 15, 20, 40, and 80. On 160 it's about a tie. But..... the loop totally kicks the g5rv's butt on 10 by far. Overall, I'm very pleased with the g5rv. It's not super noisy either. Don't omit winding the recommended coax choke for it. It helps. I also put a W2AU unun on the feedline near the rig. These make tuning for the lowest swr a lot less work with the tuner and a lower swr. I can get 1.5 to 1 on all
band except 160 which is 3 to 1 at best.
