mike65 Posted May 28, 2013 Share Posted May 28, 2013 What are you installing it in? TThere are a choice of mounting bars. This is one type. http://www.ebay.co.uk/itm/CLANSMAN-MILITARY-ARMY-RADIO-MOUNTING-BRACKET-PRC-353-AND-321-/330927135253?pt=UK_Collectables_Militaria_LE&hash=item4d0ccb5a15 Also can be mounted on single rails on a plate with anti-vibration fixings. Definitely a coax and other cable fro 353 to ARFAT and ARFAT to TUAAM Need to look up cable numbers as I am also missing a second set.

Dougy FV432 Posted May 28, 2013 Share Posted May 28, 2013 Hi Arnie, Which position are you planning on fitting the radio into? Have you got the radio table fitted behind the automotive batteries? Have you got any cables left in from its original fitment? Mike has found the mounting tray that the 353 will sit onto in the table. Depending on which antenna mount you want to use, determines what length cables and brackets you need. If you go for the front mounted tuaam, by the driver then the cable lengths are fairly easy, but the brackets are harder to find. If you want to mount by the rear door, then the brackets might be a bit easier to come by than the front, and you will need a long 12core and bnc lead to go from the Aarfat to the radio, and a short 7core and bnc from the aarfat and tuaam. Don't forget you might need the short bnc lead from the tuning ring at the antenna base to the tuaam. Also some antenna mounts don't have the link wire from the antenna mount to the tuner ring. Obviously the last couple of points relate to whatever position you go for. I will post some pics at that other place you know! Also I will give you that link for the clansman manuals Dougy Quote Link to comment Share on other sites More sharing options...
g0ozs Posted May 28, 2013 Share Posted May 28, 2013 Arnie I have a lifetimes supply of untested ARFATs - PM me off list to sort something. I can probably do the 12 way cable let me know what length you need Regards Iain Quote Link to comment Share on other sites More sharing options...
mike65 Posted May 29, 2013 Share Posted May 29, 2013 Hi MikeIts all going into a FV432. Arnie Well in that case this maybe of interest www.ferret-afv.org/manuals/clansman_wiring_harness_and_control_boxes_description.pdf I have an anti-vibration mounting kit will get part numbers later Mike Quote Link to comment Share on other sites More sharing options...
AlienFTM Posted May 29, 2013 Share Posted May 29, 2013 Correct me if I am wrong (I often am: it was a long time ago). Wasn't the ARFAT part of the VRC321 installation? My memory suggests that 353 goes radio - TUAAM - antenna? Quote Link to comment Share on other sites More sharing options...

g0ozs Posted May 29, 2013 Share Posted May 29, 2013 (edited) Alien The combinations were 353 - ARFAT - TUAAM - VHF base - Base No 31 - 2m rod 352 - initiate - TUAAM - VHF base - base No 31 - 2m rod 321 - TURF25W - base No. 31 - 2 to 4m of rods 321 - Amp 250W - TURF 250w - various antennas The ARFAT is only used with the 353 - it is a switched power attenuator used to protect the 353 and TUAAM from a mismatched antenna in high power transmit following a frequency change until after the TUAAM has had time to match. It is needed because the TUAAM was originally part of the Racal product family that includes the 351/352 but the 353 can produce much more power. I expect that there was a Marconi tuner intended for the 353 that never made it into service leading to the use of the ARFAT to enable 353 to work with TUAAM but I have never seen documentary proof of that. The 321 never had an auto tuner in the Clansman range - MEL did make one intended for the 321 although I was less than impressed with the one I tested and I wouldn't have bought it either!

Regards Iain I have a bit of a weird 353 that has a Turf position instead of Arfat, will see if I can get a pic of it for the weekend.

Dougy FV432 Posted June 6, 2013 Share Posted June 6, 2013 Here is the 353 radio with the turf position instead of Arfat Dougy Quote Link to comment Share on other sites More sharing options...
mike65 Posted June 10, 2013 Share Posted June 10, 2013 Arnie Apologies for delay. Thus is the anti-vibration mounting for a 353/DMU (well one rail) I am led to believe this is what was used in armoured vehicles Install kit was NSN 5820-99-794-2635 Was checked in CES P45411-1 (whatever that one is) back in 1990.
