|Not very happy with Diamond, Right now.
||Time Owned: 6 to 12 months.
|I rate this one at a dismal, 2, as I have had a few problems, and am beginning to wonder if Diamond might not be having some QC problems, right now.|
First, let me explain, I am a darned loyal Diamond user. I run an SG 7900 on my mobile, and on the mobile I keep in my wife's car. I have an NR770HB on my motorcycle, and ran an SG7500 on my work truck, sort of. It has been OFF the truck, more than it has been on the truck. My backup antenna for the truck is an NR77oHBNMO. I also run Diamond antennas for my base (510X) and HT (SRH320A), as well as a few other applications. Yes, I have always been loyal to Diamond, as I have always been happy with their products, until now.
I bought my first 7500, after about a year and a half of great service from my 7900's, and considering that several friends, whose recommendations I value greatly, recommended the 7500, HIGHLY, I decided to get the 7500 for the work truck, as Diamond does not recommend the use of a 7900, on a large commercial vehicle, due to it's length, and the vibrations causing trouble.
The first 7500 I bought, from HRO Anaheim, was purchased new, but when I got it to work, my next day at work, I went to take it out of the package, to install it on my existing NMO mount, and it fell apart, in two pieces, in the middle of the lower coil. I chalked this up to being an anomaly, and a week later, took it back to HRO, for a replacement.
HRO was gracious enough to replace it, and even looked it over thoroughly, saying, "Yep, it was NOT stressed, it was a defect". They gave me another new SG7500NMO, and off I went.
A month and a half later, I am driving down the road, and hear a "clinking" noise, on the catwalk, behind the cab. When I stopped, I looked to see what it might have been, and sure enough, the top section was missing, from the middle of the top coil, up.
Now, this antenna, is mounted high, above the rear window of a 2008 Freightliner daycab, and behind a fiberglass fairing, centered on the cab. For it to have been hit by anything, the fairing would have sustained serious damage, and the trailer likely would have, also. No damage to either.
A month of emails later, between Diamond Japan, me, and RF Parts, their US Distributor, I finally got an RA number, to return it for them to look at it, and "see if it is covered under warranty". I got it back 2 days after shipping it (Great turn around time) with a note that said:
"Antenna was hit by something. Lower element is bent. Diamond Japan is warranty this antenna".
While there WAS a SLIGHT bend in the section between the lower coil and the middle coil, I can assure everyone, it was not from hitting ANYTHING.Could it have been mishandled, or some other treatment cause the slight bend? Sure. But it did not hit anything. Even if it had, do not these antennas have enough ruggedness, to withstand a normal strike, from a foreign object?
While I am grateful that Diamond Japan covered this item, and got it fixed, I am not very confident that anyone will receive proper service, when they turn to RF Parts, for their warranty work, and seriously doubt that Diamond's QC is what it once was. While I have always been very happy with Diamond antennas, in the past, I would look for others, before I settled on a Diamond, nowadays.
Sorry, I must rate it a dismal 2.
