excellent
|
Time owned: 3 to 6 months

This is an excellent performer, best mobile receive antenna I have ever had. Beats the Diamond SG7900, which broke 3 times and was given up on in favor of this antenna. Hope it holds up in the long run, as it sure is the nicest mobile antenna I have ever had the privilege of owning after 23 plus years in hamming it up. 73!
To add to my previous review: make sure you have a strong enough mount to hold this antenna in place, as it very large and will load up quickly going down the road. I am running mine with the Comet HD5M mount, which works very well with it.

OK performace/Awful service

So up until this point I thought the 790a was a good antenna have had no problems with it.
I have had it for a little over 6mths and we had some really cold days here in WY recently and the lower phasing coil just snapped as I was driving down the road. In falling off the truck the upper coil was damaged as well. In my phone call to NCG (US distrib for Comet) I was informed that they would not be replacing the coils because it was normal wear and tear and they were "maintenance" items. The rep said if the SWR was good before it broke then there was nothing wrong with the antenna and would not warranty the coils that broke. But they would sell me the coils at $12(lower) and $9(upper)and charge me $8 to ship it to me. So at a 1/3 of the cost I could use it until it breaks again and in the reps words I "should be lucky they offer replacement parts and don't have to buy a new antenna". Well you can bet it wont be another Comet ever again!
So be aware that the warranty is non-existent unless it is electricaly wrong from the start. I am really dissapointed with CS and would not spend the $$ again.

Heavy duty
|
Time owned: 3 to 6 months
|

This antenna gives me a little more gain than the SSB-7, but at a price. The construction is very strong, with heavy duty elements. With this comes greatly increased wind loading compared to the SSB-7. I am very concerned about using this with the SO-239 mount through the roof (sheet metal) of my Ford Explorer due to the wind drag generated at highway speeds. If selecting this antenna, look for a sturdy mount and enjoy a very good antenna.

Takes a licking
|
Time owned: 6 to 12 months
|
After most of a year & close to 200,000 (team operation, truck never stops moving) miles on my left mirror mount this antenna is working great. The base of the antenna is about 8.5 feet off the ground so it can't help but get out great, and get hit by trees. I had to replace the lower inductor ($12.00) once after a few too many tree hits, but that's to be expected in this application. Puts out a good clean signal.
My installation is less than perfect as Freightliner Columbia trucks are made with a lot of fiberglass and make poor ground planes. SWR measured with a MFJ-259B is less than 1.7 142-149 MHz.
1.4 143.5-144.75 Mhz,
1.5 145-146 MHz,
1.6 146.25-147.25 MHz.
1.7 147.5-149 MHz
The sleeve for the fold-over hinge must be tightened with pliers or it will vibrate loose.
