works well for me  Time owned: more than 12 months
I have a Kenwood TH-F6A that works very well. I was looking for a little more gain and picked up the Diamond SRH320A. I noticed right away being able to hit the repeaters in the area (NYC) solidly with lower power than with the stock antenna. Where I used to have to run on high power for full quieting (5W), I can now hit with low power (0.5w). The radio doesn't fit in the shirt pocket anymore, but being able to run all day on a battery charge is very nice.

Meh.......  Time owned: 0 to 3 months
Guess it would make a decent replacement to a lost, or broken, OEM duck. I bought one along with the purchase of a yeasu vx-6r, due to reading reviews posted here. I'm just not seeing the magical awesomeness that everyone else seems to be experiencing. Either the kenwood ducks really suck, the yeasu ducks kind of suck, or the antenna I received just plain sucks compared to others rolling off the same line at the plant.
My performance experience was that the diamond, compared to the stock antenna, was that the diamond had such a "maybe" dicernable difference.... Perhaps only because of an almost double length from the stock duck. The best I could detect was a minuscule reduction in the sizzle on a fringe repeater. Certainly not worth $50. And, I purchased the radio for its submersible capability. Something I doubt the diamond has. My plans were to plasti-dip from the tip, to half way of the base. Glad I tested it before the modification! Like one of the other reviewers stated, better to put your money towards an extra battery. Amen.

Best Money Spent!  Time owned: 0 to 3 months
I am nuts about antennas. I have tried so many and this product is by far "THE BEST" on my Yaesu FT-60. It performs flawlessly. I am able to hear repeaters with better signal strength and get into area repeaters on low power "Full Quiet" something that I haven't been able to do in a long time. This HT Antenna is "The Goods" in performance. It's well built.

diamond SRH320 triband HT antenna  Time owned: more than 12 months
I've had the antenna for several years. Last week I got curious about whether it was REALLY a good antenna that the Mfr claims. Turns out it's pretty darn good. I compared it to my TH-F6 HT original antenna. I set up my field strength meter and went thru all three bands comparing the two antennas.
Two mtrs: The Diamond was margionally better than the Original. The meter showed 50 for the original and 70 with the Diamond.
222 MHz: Set the meter to show zero with the orginal. The Diamond pegged the meter.
440 Mhz: Set the meter to show zero with the original. The Diamond didn't peg it but the reading was 75. The meter scale max is 100. Definitely better.

'Nuf said?? :-)

Good alternative  Time owned: more than 12 months

I paired this antenna with a Yaesu VX6R. This antenna is a vast improvement in gain over the OEM antenna. I was able to hear some stations on simplex marginally better than using the stock one. I would recommend buying and using this over what is supplied by the manufacturer for your HT.

Wonderful!!!  Time owned: more than 12 months
If I could give it 10 points, I would. Perfect antenna for the Kenwood TH-F6A HT. The stock rubber duck works but this is like color TV compared to black and white, for those of us who recall those days. I can hit Mt. Diablo using 5 watts from my home QTH, almost 85 bird miles. Loud and clear. I highly recommend this antenna, I've had it for 4 years now and it's holding up well. Tremendous performer.

By far the best HT antenna  Time owned: 0 to 3 months
I bought this antenna a few months ago because I had really been needing a really good HT antenna that would last me a long time. When I first put this on my radio, the difference could be noticed immediately. Compared to other antennas like ExpertPower that I had been using for a while, this one just blew them out of the water. I live right on the edge of my local repeater, and all of the previous antennas I used were marginal at best, and I had to go outside of my house to successfully get into the repeater. However with this antenna, I can now go anywhere inside my house and get the strong signal tail tone. Not only that, but I can even go in my basement and it still works great! It's truly astonishing to me that an antenna can perform so well. Both VHF and UHF bands perform great, and I haven't noticed any kinds of issues with the antenna.

Even though it's relatively large in length, the upper portion of the antenna is very thin which gives you the illusion that it's smaller than it really is. Because it's so flimsy, it seems like it would be really delicate, but it's able to bend back to its original shape no matter how bad you bend it. I couldn't really tell you how extreme you have to bend it to where it won't go back (because I don't want to try), but so far it has always been able to go back. It also looks very good on the small HTs that we have nowadays. It doesn't make your radio look lopsided with a huge antenna. It performs very well and it looks very good.

The $50 price tag should not deter you from buying this. It is literally the single best performing HT antenna I have ever seen, and you won't be disappointed. I wouldn't say that if I wasn't 100% certain that it's the best. You really do get what you pay for in this case.

Much better than the stock Kenwood  Time owned: more than 12 months
I have only used this on 2m and 440cm, and most of the testing was related to 440cm. While I do notice a bit better 2m repeater contact in shadow areas, with 440cm there is a spot that I have worked a marathon three times past years. The first year I had the stock antenna on the TH-F6 and had to go to my spare battery before the end of the day since I had to use 5 watts to make the repeater and hold the radio just right. The next two times with the SRH320A I ran at 0.5 watts and had no trouble with the repeater, and the battery lasted all day. I did test the two antennas when I first had the SRH320A and the original TH-F6 antenna was still working the same as the year before.

Doing bicycle mobile, I had to take the radio out of the backpack on most of the parade route but with the SRH320A, I can leave it in the backpack for most of the route.

However, a mag mount on the roof blows this away but then I can not shadow an official that way, so I guess I will keep using the SRH320A.

Oh, there is one issue. Compared to the stock antenna this is over twice as long with the attendant getting in the way of a longer antenna. But that is one of the tradeoffs.

A great rubber-duck replacer  Time owned: 3 to 6 months
Antenna works well. Using it on a vx-6r and it is much better, by far, than the stock antenna. Construction quality is good.

I am able to get into local repeaters using less power and the rx has impoved. I have bent the whip pretty bad a few times and it always returns to its original shape.

If you are looking for a good replacement antenna this is a quality choice. Even though it has a higher price than others... it's worth it.

Better than others  Time owned: 0 to 3 months
Tested using APRS while riding a bike in town on a somewhat usual route. Previously I've used a Maldol MH-510 and a Diamond SRH-519 in the same area. Setup is a TH-d72 with smart beaconing enabled. I was picked up more often with this antenna then with the SRH-519 (as expected), and about as well as with the MH-510. I was even heard direct from a digipeater 50KM away, recorded by It is much lighter and rig-friendly than the MH-510 though. The top mounted matching coil on the MH-510 feels like it is putting extra stress on the antenna connector, and of course does nothing on 2 meters, I got none of that feeling from the SRH320a.

When I first put it on the radio I had to bump up the squelch a notch or so. I take that to mean it is better at picking up RF energy than the SRH-519.

It is a large antenna. It is an expensive antenna ($50 just seems steep). It does find it's way into your armpit when your HT is on your belt. But it works.
