Look at this piece for the improvment of your mobile system, for sure the noise level went down to non apperance on th scale, mind you need to of these for the 3.5MHZ, I only got one here with the dealer, it was just for show and I managed to buy it from him.
Here is the link
I think that it's not so simple, my friend.
Did the noise floor go down while the signal stayed the same, or did the antenna just get quieter? Also, did you try the grounding mat on your vehicle? Does the antenna transmit better? Usually, when an antenna receives better, the noise floor goes up (but so does the received signal strength) - at least in my experience, and all other things being reasonably equal.
There are several antennas out there on the market that are very quiet, but they are also very deaf.
Unless you have a fibreglass vehicle like a Corvette or a composite bed like a Tacoma, it seems to me that the appropriate way (imo) to correct a poor antenna-to-vehicle body ground is to install grounding straps as needed. For non-metal vehicles that need some metal for the antenna to "push against", metal (adhesive copper) sheeting that's grounded to the antenna and chassis seems to me like it would be the way to go, and the more the better.
I'm confused as to why you can't use more than one ground mat for 6M. It seems counter-intuitive that more ground is less better unless it's a tuning issue and these things are acting like radials.

Reason: just cleaned things up a little
Good Evening you my friend.

This piece act like earthing the whole car and also as a redials.
This is on my big 4 wheel drive car, In my small 911 which I bought only 3 months back never had a problem with the sort of noise I am getting in this car, in the 911 I use the GT-975D and it is all ok.
Please check on this piece my friend
My best regards to you

Thank you for that, Rasheed.
It makes sense then that since the MAT50 is acting like a radial that it would need to be "tuned" for 6M (although I still don't understand why two of them can't be used - maybe it's a capacitance thing... just a guess).
I owned a 911 (996) myself for a number of years and the only thing the paint saw was the washing, wax, a terry cloth, and the occasional buffer. hihi
It was by far the best car I have owned and I couldn't imagine putting an antenna on it.
It's a different story for my truck - the F150 has two antennas.
In any case, if I have a vehicle grounding problem that can't be solved the usual way, knowing that the MAT50 is out there to consider would be very useful to me. Thank you for sharing this.

Reason: changed MAT-50 to MAT50
Thanks my friend, mine is 911 Carrera S 2008.

Thank you and 73 my friend
I always loved VXR 4 wheel drive, I have one now and it is a real good one on the sand, but because now a days I go out up north with all of the A7 group and they drive GMC pickups, I had to order one in order to have more place for my electrical generator, ice box and my bed, that why I have order the high siera antenna to attach to this car.

Thank you again my friend and 73 from Qatar
