The SSB install was a multiple step process for us. Step 1 was to mount the transceiver (the radio) at the nav station, run wires to the antenna tuner which is mounted in the very back of the boat in a lazarette near the stern, run power to the radio and connect it to the modem.
Here is the finished product so you can get a sense of the goal:
Our radio is big and unlike some other big radios it doesn't have a remote front plate which would allow us to mount the bulky part somewhere out of the way and put the front plate at the nav station. This wasn't much of an issue for us as we would have ended up putting the bulky part at the nav station anyways. I can tell you for certain that having a smaller radio would have made it a lot easier.
The other issue is that the plugs on the back of any SSB are big and you have to take into account their size before mounting the radio. Here is the back of the SSB and the modem with all of the various connections:
The wires that connect the radio to the power and the antenna tuner are run through the ceiling (as are most wires in our boat, this keeps them out of the way and less likely to be sitting in standing water). Thus, the first step was to pull out our stereo, VHF radio and the woodwork that was added to mount those.
Then I disconnected the wires from the transceiver, removed all of the ceiling panels in the aft cabin, removed all of the stuff in the back lazarette and then ran the wires from the nav station all of the way to the back of the boat. After 30 minutes of collecting fiberglass splinters it occurred to me to wear gloves.
There is a standard mounting bracket for our radio which, of course, does not work in the space we have for the radio. We bought some metal shelf brackets which were the perfect height to bolt to the shelf underneath the radio and screw into the mounting holes already built into the side of the radio. Of course, the brackets were too long to fit underneath the radio so Carol cut a section off of each bracket. I painted these with black rust paint. I also took three pieces of marine grade plywood, glued them together and painted them to use as a block to provide support for the back of the radio.
Now, another fun part. How do you drill holes in the shelf? The drill won't fit on the top and will only kind of fit underneath the shelf. After some choice swear words I managed and was able to bolt the brackets through the shelf (with washers to distribute the weight on the wood).
Finally, I wedged the radio into position. It barely fits which is perfect because it has no where to wiggle to. It is wedged up to the ceiling at the back with the block and is bolted on each side to the brackets which are bolted to the shelf and the front of the radio rests on the shelf front. It is solid. Even if we get rolled, it should stay put.
And voila - it's mounted. Well, that is, after getting everything back together, realizing I had knocked a connection on the CD player loose, fixing that, and putting everything back together again.
Next stop, the tuner.
