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.

A powerful antenna that acts like a homebase verticle  Time owned: 0 to 3 months
This is one great antenna. Being in the UK, Great Britain I had a problem finding a dealer however I found one in the US. I have an icom 92d HT. The rubber duck did what it was meant to do but it was no way a great antenna. My new antenna came this morning after waiting about 2 weeks and came in a square box with the antenna in a yellow sleeve. It is 35cm in leigh and does not look out of place. On the yellow sleeve its says the gain on 70cm is 15dbi. There is a repeater about 25 miles away. I am in a valley surrounded by houses. I could never open the repeater. Now the reason I gave this a 5. Sitting on the sofa inside the house I can open this repeater. It's mad. Even with the mobile car antenna I could never do that. Rx is very good. I can pick up signals that I could not do with my stock antenna. This is one powerful antenna.

Super tri-band HT antenna  Time owned: 3 to 6 months
I am very pleased with this antenna. It outperforms the stock duck in both RX and TX. Would recommend it to a friend..

Great Tri-Band TX  Time owned: more than 12 months
This is an update after two years (see KJ4AXU review) and the antennas have performed exceptionally well on 2 meter, 220, and 440. Also listen to police and fire bands with it. Worked Paddlefest in Cincinnati this year and worked up and down the river with just this for an antenna and it worked great. Other folks had areas where they dropped out, but I made solid contacts throughout. Probably going to get a third one for another handheld. Recommended to several friends and they are quite pleased as well.

Great choice for TH-F6A  Time owned: more than 12 months
Based on my previous experience with Diamond products, I decided to buy the SRH320A at the same time that I purchased my TH-F6A. I have never regretted it. Performance is far better than the stock Kenwood antenna on all frequencies that it is designed to work.

Factory specs:
The SRH320A is a 1/4 wave on 2 meters and 220 MHz, a 1/2 wave on 430 MHz. This antenna terminates to a 50 ohm SMA. It is also suitable for wideband receivers which feature an SMA connector.
It is also optimized for receive on the 120, 150, 300, 450 and 900 MHz bands.

My SRH320A is a fine TX/RX antenna on 144/220/440. It also receives very well on the air bands as well as VHF and UHF public service frequencies. Just like Diamond said it would. I can't rate it on any other bands because I haven't used it there.

If you have a TH-F6A and need improved performance on all 3 bands I can recommend it without hesitation.

As Advertised  Time owned: more than 12 months
The SRH320A is typical of Diamond Antennas. If you want the best on VHF/UHF, get out your wallet, and don't be shy.

It's the bomb. I wouldn't part with it. To reiterate what some have said earlier:
DO NOT BUY THIS IF SW / AM BROADCAST RECEIVE IS YOUR "THING". Dreadful below AIR band (of which it is GREAT at). Again, As Advertised. Diamond makes no bones about the optimization of the antenna for 3 Amateur bands and 5 receive bands starting at air. Vertex products (and others) with wide receivers will work GREAT AT AND ABOVE the air band.

AMAZING difference on 70cm. Has a taper from stout at the lower loading coil, upward to a very fine upper section. I find it comfortable to wear on my VX-6R after removing the pitiful new Vertex clip and putting on an "old style" Vertex upside-down and out belt clip. The clip gives it just enough pitch away from the body to make it comfortable. Very light and durable.

The moral of the SRH320A story is:

1. Read the manufacturers description and specs and don't EXPECT more.

2. You get what you PAY for with Diamond.

Works OK  Time owned: more than 12 months
I have to be honest and say that this is really a comparison of the SRH320A with the big brother SRH999. I originally bought the 320A because I wanted an antenna that would work specifically with 1.25 M, but I found out that the 999 actually works better on 1.25, even though it's not designed to work with it specifically. I'd much rather have a bunch of 999's for all my radios than 320A's, actually. But for all that, I have to be fair and say it's a good antenna. Just doesn't work as well as the 999, which I'd readily purchase, even though it's a bit bigger. With this one on a 1.25 radio, my son can't hit repeaters as well as with the 999.

Fairly Good  Time owned: 3 to 6 months
While I know it is marketed as a VHF/UHF triband antenna I had hoped it would work in HR for receive on my 6R, but it is dead. I have to put on the stock antenna to receive anything below FM broadcast. Not really a fault of the antenna but I do like to do some SW listening...
