very good Time Owned: more than 12 months.
I have this antenna up at 40 feet ,works very well with low load on the mast ,helps me with 2m/70cm out to about 40 miles i live in very hilly terrain so vhf can be awkward all i can say is it just works as it should ,it has out lasted 3 x 510s ,which snapped in high winds ,simplicity and robustness ie all i need

Great, very convenient Time Owned: 0 to 3 months.
I was given this antenna by a GMRS operator who mistakenly purchased it thinking it was for GMRS. Within a few days, I installed it at the home QTH side mounted on the tower just above the roof level. It replaced two mono-band commercial VHF/UHF antennas. The reason I replaced the two with one antenna is for convenience and wind load.

After 30 plus years of trying to achieve the *highest* gain and talk the farthest distance, I have reached the age of ham maturity and have begun to think practical and simple. The Diamond X30 seems to be a dependable, simple antenna that works all the UHF/VHF repeaters I am interested in working.

It is based on the same principle as a Larsen NMO-270 dual-band mobile antenna, a 1/2 wave on VHF and stacked 5/8 wave radiators on UHF. It doesn't have a lot of gain, but when super gain isn't needed, then gain doesn't matter.

Keep in mind that the sum of all RF goes through a small disc capacitor. Most dual-band antennas are designed the same way. I would not attempt to run more power through the antenna than is rated, or you'll smoke the disc capacitor.

Overall, I like the X30 so far, and it is performing as expected! Highly recommended.

Great Performing Antenna! Time Owned: 3 to 6 months.
I think the Diamond X-30 is unbeatable for it's price and performance. I replaced a dual band ground plane base antenna which had become erratic and it was like night and day. I can't recommend it more highly. While I had considered getting the X-50 model, nearby trees (and $40 less) made me decide to go with the X-30. I am very glad I did!

Awesome Antenna Time Owned: 0 to 3 months.
This little dude works great! I can hit and receive repeaters up to 100 miles away here in San Diego all the way to Orange County and south of LA. The match is dead flat across the 2 meter spectrum and also on 440 band. I have it mounted on a small satellite pole used for an old dish and it size is perfect as is a super easy to mount because of its size. I would buy again for sure! Diamond antennas are well made and top quality! Great for antenna restriction areas... easy to hide

Replacement for Existing Time Owned: 0 to 3 months.
Have only had this atop the 40' tower #1 a couple of weeks but works great. Tested the SWR "sweet spots" prior to climbing. This replaced a Discone for better performance on 2m & 70cm. Installed new, better coax too. What a difference!

Can"t go wrong** Time Owned: more than 12 months.
I would say the X30 is better and cheaper than the X50***

Terrific Time Owned: more than 12 months.
Just a great UHF/VHF antenna. I bought it used about 10 years ago, and it is still working great. Good SWR on both bands. Well built, yough as nails. Highly recommended.

Good Bang For The Buck Time Owned: more than 12 months.
I Have two of these up in the attic, one for ham and one for GMRS. This antenna works well, gets out well, low profile, does what it was billed to do. I have also re-tuned many for commercial and GMRS use for others. Simple and rugged design inside and easy to tear down and trim for higher frequencies. Easily moves up to 151-153Mhz and 460-470Mhz center frequencies. I give a 4 only because the factory tuning is not consistent. Some of the reviews say the SWR is a bit high out of the box. I have noticed this too. Before re-tuning I check to see where they are (hence, how far to go 1/4" at a time), and VHF is usually spot on at 146, but have seen as low as 144, UHF is sometimes centered at 446, but in the last batch I re tuned, one was 435 and another was 457, usually they are 450-452 center out of the box. Add 30-50 feet of coax and your radio most likely won't care, but they could do better. Over all, a good value, and you will never notice the 1.5dbm difference in the X-50 so don't feel bad about not springing for the extra $30.

Low profile, good performance Time Owned: 0 to 3 months.
I recently moved to a small condo and have landlord restrictions when it comes to mounting antennas. I have a small terras (ground level) and I installed a 43 feet fiberglas vertical for shortwave but needed a dualbander for accessing local repeaters both FM and Dstar or Dmr. The X30N is really low profile and I mounted the antenna on a 12 feet fiberglas rod. Even on this low height I can access repeaters up to 30 miles away with 5 watts from the handy. Great performance.

Great Antenna! Time Owned: more than 12 months.
I run this antenna into my Wouxun handheld and it does all I need. Can hit all the local repeaters and more with it. Its easy to mount, and has low visibility so very little in the way of eye pollution. Would I buy another one? Yes I would! Another great product from Diamond.
