Through the glass has been popular with me and I have used both CB and 2m through the glass with good success. Back in 1971` transferred to GTMO, Cuba - had an antenna for CB on the car but not one for the house. Stripped the rubber protector off of RG-8 to 108 inches baring shield. Skinned the shield back down the phonolic insulator to the 108 mark. Tied a string on the end and hoisted it into a tree. Talked back to the U.S. almost daily. SWR was just under 2:1.
Theory - it's either going to work, or not going to work. If running a cable back to the TOAD use the formula for determining the legth of coax needed for a quarter wave. Use a multiple of that length to achieve the distance to the antenna on the car. There will be some loss with the longer run of coax,
If I were to do the through-the-glass I would put it on the front windshield above the driver. I tried a CB through-the-glass on the previous MH and through the double insulated side window. It worked, but not as good as I would have liked it.

Darn, getting me interested again!

Right on - i've come to the conclusion that getting a good antenna set up (especially mobile) requires a dose of wizardry. It makes me recall the days of B&W TV, rabbit ears and aluminum foil or the ever popular "sit right there, hold your arm out and don't move, the picture is perfect" method. I'm getting interested in as well.
