mounting a C80 next to VHF and other eqpt

reading through the raymarine manual it advises to mount the C series around 3 feet to 1 metre away from other radio equipement......this makes it slightly impracticle for me as i want to mount it quite close to my vhf dsc radio ....i also wanted to mount my gps onto the console as well which will be with probobly around 12" distance away .....in fact my whole dash layout is impractical for that kind of distance ....my fm ariel is a shark fin type which will be hidden uder my windscreen ....is it worth scrapping that idea and going for an A frame mount with a VHF splitter

questions for C series owners .........have you mounted your radio closer than what raymarine recommend and do you get any interferance from radio equipement and if so what did you fit to overcome (filters etc)

thanks in advance

Ian

Hi, my C120 display is right next to my VHF set and I do not experiance any problems.

I believe the Raymarine advise you are refering to only applies to the antennas, not the head units.

My GPS Antenna is in the top of the dash, and the VHF is on the top of the A-Frame so I don't have this issue.

Nasher.

For optimum EMC performance, it is recommended that wherever possible:
Raymarine equipment and cables connected to it are:
At least 3 ft. (1 m) from any equipment transmitting or cables carrying radio signals
e.g. VHF radios, cables and antennas. In the case of SSB radios, the distance
should be increased to 7 ft. (2 m).
More than 7 ft. (2 m) from the path of a radar beam. A radar beam can normally
be assumed to spread 20 degrees above and below the radiating element.
The equipment is supplied from a separate battery from that used for engine start.
Voltage drops below 10 V, and starter motor transients, can cause the equipment
to reset. This will not damage the equipment, but may cause the loss of some information
and may change the operating mode.

Thanks Nasher ....I copied this out the manual ......i dont have a choice really but it does highlight the words wherever possible .....so they must know the impractabilities of doing this

cheers

Ian

Hi Ian
i have the C80 fitted on top of the console and the radio in the console aprox 2foot away. The antennas are on the A frame about 1 foot apart with a radar reflector in the middle of them, i have no interferance on either gps or radio.
