10 Years plus!!

I bought this antenna at RF Products in Rockledge Florida in 1995.This antenna has been exposed to extreme Elements from 95 degrees in Florida to Subzero Temps in Connecticut with Frezzing rain and snow. The SWR has never changed and the performance is as strong as the day I put it up in Florida. Remember to use low loss Coax like Times mirror LMR 400 or Belden 9913.The antenna performance is amazing for it's size(just over Ten Feet).I used it on 60 FT Towers and Chimminy mounts systems also in one installation I used on a air vent PVC Pipe It's light enough not to worry about damaging a thing. Give it a try you won't be sorry.

I own two of these antennas...I needed them for rptr sites with both 220 and UHF on them...and noone else except Diamond makes an antenna that covers both (well MFJ does now with their QUAD band models....I am looking at those for a 6/220/440 site...) I used one for all three bands at one site but the 2m side was a digipreater (not a voice machine). In all cases, the operation of the antenna was great! It met or exceeded gain and coverage expectations.....I have compared it to a DB420 DB Products dipole array and while it is not 9-11db like the DB420, it does hold its own and performs quite well at the same height, etc....I DID find the sun and Gulf Coast of Texas weather cracked the fiberglass in one spot on one of them...luckily I was able to drain the water out, repair the crack and the antenna is still working fine! No loss of service (BUT remember it is a cheap amateur antenna compared to a DB420) I WOULD not use this on the TOP of a tower or expect it to survive lightning or ice (I suspect iceing caused the crack in the 1st place)....for the price, it performs GREAT and for home use, I HIGHLY recommend it!!! I think it could be beefed up for rptr use...but then the construction internally has disk caps across phasing sections...not a good design for rptr service! I would rather see NO caps inside or something heavier than the small ceramic caps they stick in there...On a building top, it has proven to be a good antenna on one rptr site...the other one was 480ft side mounted on a tower...was up in the air for 4 years with no problems but when it came down, it was showing bad weathering on the radials and fiberglass.

Wow!

In order to accomodate a new radio which operates on these bands I replaced a 2 meter vertical "stacked co-linear" advertised as having 9db gain. Though I have always been happy with the previous monobander, the comparison would be flashlight to searchlight.
The big comparison test was talking to a friend in a nearby town with a ridge between us. To communicate before, I had to open my squelch and then listen through the hash; he never wiggled my S meter. Now, we have each other 1/2 scale on the S meter, and only a small amount of white noise!
Easy to assemble, took me 20 minutes from start to transmit. Obviously VERY well engineered-will last for decades I'm sure.

I have owned the Comet CX-333 for approximately 4 years. It has performed well in all situations and has withstood the elements including heavy winds quite nicely. It is solidly built and very clean looking and "low profile" only 10.5 feet high making a nice addition to any antenna "Farm".

Great Antenna

I've had this antenna up for about 6 months now and it works fabulously on 144, 220 and 440 MHz. It replaced a Cushcraft AR-270 and it out performs the AR-270 in both receive & transmit. Also, the materials Comet uses and their machining is superior to that of today's Cushcraft products!

I have had one of these on my roof for a couple of years now and it works great. It is connected to my Kenwood TM-742A tri-band VHF/UHF rig through a Comet triplexer and this seems to be the perfect multiband base station antenna system. SWR curves are where they should be and the performance on the air is excellent on all three bands; 2M, 220 and 440. Weather has not bothered it at all either.

Great multi-band antenna!
|
Time owned: 3 to 6 months

I purchased this antenna to fill my need for a multiband VHF/UHF base antenna with excellent gain, per the suggestion of a local ham. I am not disappointed!! It comes with mounting hardware, and works great with a triplexer! Great gain, I have heard 2m activity that I didn't even know existed before!
I highly recommend this antenna to anyone who is searching for a good 2m/1.25m/70cm base antenna. It stands 10.5 feet high, and is easy to ground.
