NR770HA plus HRKS mount - Works well Time Owned: more than 12 months.
I bought the NR770HRKS package. You mount it using double-stick adhesive. I mounted it to the rear most side window on the driver's side. It was on one car for about a year. I moved it to a second car this year.

I was able to remove the mount by drawing picture hanging wire through the double-stick adhesive. The window cleaned up easily. For the mount, I just sanded off the remains, put a new coat of paint on and mounted it on the new car using black, wide, heavy duty outdoor double-stick tape available at a big box hardware store.

They key is to bend the mount's flexible tabs to conform to the mounting surface. The tape will not hold the tabs down if the tabs are flexing back away from the surface and highway speed winds will eventually cause problems. So form it first. Then remove the protective backing. Then adhere. Works great.

The antenna itself also works great. The quality of the machining and finish exceeds other antennas I have used.

I would definitely buy another.

A solid performer Time Owned: more than 12 months.
Over five years of NR770HB ownership and it continues to perform well. I have it positioned on a Diamond K9000LRMO motorized mount on the top of my SUV luggage rack.

SWR is beautiful on VHF/UHF. I blast 5 to 50 watts for repeaters, APRS and simplex use as needed.

I have forgotten to lower it twice and it survived each instance. See my review of the mount here: http://www.eham.net/reviews/review/128319

It works so well I purchased another NR770HB for temporary projects, or if the one on the daily driver requires replacement.

Maybe the best 5/8 Antenna Time Owned: more than 12 months.
Using this antenna since 2009 on my car travelling around Italy, and on MSC Musica cruise ship in Mediterranean sea mounted on a magnetic base bracket!
I never had a problem.
I think this in one of the best mobile antenna: low SWR both in V and U bands, good compromise between performance, price and size. Excellent building material.
NR770HB (B for black version) is "almost invisible" on car. Bought another one for home APRS Station. I love it!

Not bullet proof Time Owned: more than 12 months.
Not overly rugged for a premium priced antenna....been running it on my motorcyle for a few years and the top snapped off this past weekend...internal spring not strong enough to keep from popping out on bumps...wrapping it with electrical tape helps....can buy a replacement whip for about $20 but a new MFJ equivalent (looks like they are manufactured by the same OEM) is $10 more....

Excellent Antenna Time Owned: 0 to 3 months.
I have the NR770HB - black colored version and use it with a magnetic mount base. The antenna does not flop around in the wind and easily stands up to being hit by tree limbs. I use it with a 5 watt Kenwood HT and the worst signal report I have gotten using this antenna on a repeater was a "59 with a little white noise". 10/10 would recommend to anyone looking for a good antenna for mobile use.

Really Good Time Owned: more than 12 months.
The NR770HA was recommended to me by a friend who has one on his lorry,Price was £20 here in the UK which did not break the bank..I have this mounted on my lorry and it really does perform very very well,infact i can say its a fab performer.I highly recommend you buying one and i promise you wont be dissapointed,My old mobile vhf.uhf antenna was like a dummy load compared to the NR770HA,I talk simplex over 30miles most days on 5 watts crystal clear contact both ways.Im thinking of buying another NR770HA for my car and fitting my yaesu ft2900 in.

5 0ut of 5 for me...This antenna is fantastic.

Love it! Time Owned: more than 12 months.
10 years and counting.
This antenna not only performs very well, it's mechanically very solid as it's outlasted 2 SUVs now. Yes, it's going to be relocated to whatever vehicle I get next so no you can't have it.

Happy so far Time Owned: 0 to 3 months.
Really happy with the performance and the construction. 40" long and sits on top of my Jeep with the base at 67". So the tip is around 8.5 feet off the ground. It doesnt hurt to look for low hanging trees while driving. The small coil in the center of the antenna does take the shock and has not bent on the two times it has been clipped. The performance is excellant so far. Just having it hooked up to a 5 watt HT and I am getting every repeater in the city plus hitting out of town machines. Diamond says there is 3dB on 2m and 5.5 dB on 70cm. I have had no complaints on my signal and some are suprised when I tell them I am running 5 watts. The antenna is rated at 200 watts so there is room to play with. My model came in black which looks better against my Cherokee and doesnt stand out like a silver antenna. This is a replacement for a Comet(Maldol) AX 95. The AX95 base is made from plastic. I didnt find this out till I opened the hatchback with the antenna in the down position. Which in turn cracked the antenna base and turned it into spare parts. If I had known that ahead of time I wouldn't have purchased the Maldol. The NR770 is metal and solid. This antenna looks good, feels solid and performes very well.

Longevity Time Owned: more than 12 months.
I have had this aerial for so many years now (silver version) that I cannot remember exactly when I first bought it, but maybe more than 10 years ago.

It still looks great, performs very well and is still in use.

I cannot fault it, hence the 5 out of 5 rating i have given.
