Really nice. Time Owned: 6 to 12 months.
Really nice antenna, I use it with a magnet mount adapter with a cord but if I want I can also use it to replace my marine radio rubber duck, button line is........ it really improves reception a lot!

top notch Time Owned: 6 to 12 months.
I have 2 RH77CA's i use one for Fire and Rescue in the 154MHZ area and one for 2M ham, on the fire and rescue side it has filled in most of the "dead spots" when other units can't get out i just hand them my HT and say try this it works every time, on the ham side it has extended the rang of my ht to the point where i now have a shr77ca or a rh77ca on every ht i own.

Simply the Best Flexible Antenna !!! Time Owned: more than 12 months.
I've been using the Diamond RH77CA for over 12 years now mainly for scanners and most recently for my portable (TH-F6A).

What I often do with friends who owns scanners: I ask them to show me what kind of signals they're getting with their original rubber duck... and then I pull out my SRH77CA and tell them – Try this just for fun… the reaction is always the same .... WOW I WANT ONE !!!

Bottom line: I never leave home without my 2 Diamond RH77CA and when I see someone with an original rubber duck on a scanner I say to myself… "..poor guy he doesn't know what he's missing.."

Well Worth The Price! Time Owned: 0 to 3 months.
After buying the SMA version of this for my Kenwood TH-D7, I was so happy I bought the BNC version for my ICom W32A. Well worth the money for the increased performance over either of the two ICom antennas I previously used.

14 years of performance! Time Owned: more than 12 months.
Originally purchased for use w/ a TH-78a, this is a very durable performing antenna. It is certainly the most durable of all my long (>12")HT whip antennas.

I've no recollection of the mfg's performance db gain claims, but this antenna really gets the signal out. I now use it with my TH-F6a HTs when on the fringes of the repeaters.

It's also my antenna of choice for use w/ window mounts for rental cars while traveling. For use with the T-F6a, it's mounted to one of Stephen Gulyas' exceptional one-of-a-kind BGA-80 BNC to SMA adapters. If you want the absolute very best BNC to SMA adapters check his out. They were previewed in the Nov. 2000 Issue of QST magazine and the May 2000 Issue of CQ Magazine. See: http://www.wa3hrl.com/smabnc/index.html

Great Multipurpose Antenna Time Owned: 3 to 6 months.
I bought a Yaesu FT-60R a few months ago and was very satisfied with the original duck antenna. A friend suggested the Diamond RH77CA.. so I ordered one from Universal Radio for $21. It is like having a new and improved radio. I can really grab the freq's in my area. Now I can hit a repeater in San Bernardino that I did not know existed 50 miles away with my HT...from my den. Great performance on VHF and UHF. This antenna is great for scanning as well.
Just for giggles I hooked it up to my Uniden BC350 scanner. Wow!! What a difference. I may take down the roof antenna. But only if the wife complains again.

whippersnapper Time Owned: 3 to 6 months.
Everyone knows anything is better than a duckie..no more about that then.

At first this antenna seemed long, but the flexibility makes it usable and wont stress the connector on the radio much at all.

I use it on a Yaesu FT-60R for about six months now. This antenna can HEAR! Like any HT, I can't get much farther than a county away indoors. However, once outside, I have even hit three counties away on Simplex calling freq.

It may be a Yaesu thng, but no, the antenna does not fully cover the SMA connector on my Ft-60R. My easy fix...when changing the filter on my kitchen Brita water filter, I noticed it had two "O"-rings on its connectors. I took both off and stacked then on the SMA portion of the radio. When the antenna screws on, it compresses the O-rings. Makes a tight (waterproof) seal, and hides the connector on an otherwise black colored radio.

Overall:
Good reception/TX
Once you get over the "too tall" size, it never has got in the way
Rugged built; better then a "bare" wire aftermarket HT antenna and the Gain is there too.

What can I say? Time Owned: 0 to 3 months.
While it's kinda long, this little whip is light and flexible enough to live with on a small HT. My dual band Alinco DJ-596 was rather lacking on 2m with the stock duck. Put this antenna on and I'm hitting (and working) a repeater that's 45 miles away. I'm sold!

Tales a licking, keeps on ticking Time Owned: more than 12 months.
Bought one years ago to replace the damaged stock antenna on the used FT-470 I bought. This radio was my only HT for close to 10 years, and went through its share of use & abuse along with the antenna. Still works great, no damage, and even the label is still on it. I recommend tis antenna if you need one that will last.

I also use mine on an FT-470, so now my HT qualifies as a weapon! 8-) Works great, takes a LOT of abuse. Just don't be surprised at that thing poking you in the back if you try to carry your HT clipped to your belt, this sucker is LONG. I think I've had mine for about 5 years now, maybe more.
