OK guys, I'm just getting my first radio setup. It's a mobile Kenwood TS-480 and I have a question about using a pass through on the cab and a couple of other questions.
Background on the truck you might need to better understand the full set up.
The hole installation is a little unique because it's not a normal pick up with a bed or hitch where I can just set the Scorpion onto a Breedlove mount. The truck is a flat bed, dump bed with a headache rack and a tool box in the rear. In talking to Scorpion he suggest that the hole antenna be mounted at least 8 inches back / away from the headache rack since that is the tallest part and the strongest thing to build and weld a mount onto. The top coil of the antenna (MIGHT) be above it when retracted. The tip of the whip will be somewhere around 14 foot above the ground. That is as tall as a semi truck trailer.
Then just to add some more problems there is going to be a 5th wheel all aluminum horse trailer behind it.
The antenna will be controlled by a TuneMatic TM-1
Onto the main questions.
SO I'm looking at using a pass through instead of punching a big hole and finding something to use as a seal or grommet around the coax.
Q #1: Do you see and issue with using the pass through?
Q #2: Where do you suggest I place chokes on the coax? The coax run will be about 23 to 25 foot just along the bed and frame to the antenna from the back of the cab so I can still dump junk after removing the antenna and tool box when needed.
Q #3: RF Grounding. Currently the bed is grounded to the frame and electrical DC ground with large high strand welding cable. The frame is bonded to the cab with bonding strap in several locations and the hood is bonded to the cab. Should I add more bonding straps and where to bond them to?
Thanks in advance.
