I'm planning to get a 2m mobile for my car -- considering a Yaesu FTM-3100R (non-removable faceplate, under $150, 5/30/65W, CHIRP compatible -- did I mention I have a limited budget?). Obviously, I'll need to mount a vertical antenna. I drive a 2015 Fiesta sedan, so have choices of fender mount (not preferred), trunk lid (edge mount or through hole), or roof mount. A mag mount that would let me toss the antenna in the trunk wouldn't be a bad thing, but I understand those are less preferred from an operating standpoint as well as prone to damage the paint. This will be a permanent mount; I expect to drive this car for another three or four years at a minimum (to around 200,000 miles at least), but if it's through-hole, I'll have to pay someone to install the antenna, as I lack the tools (and skills) to remove and replace the headliner for a roof mount or drill a large hole in the roof or trunk lid (and make it not leak). So, first question: is there a significant performance difference between a trunk lid edge mount and a trunk lid through-hole? Ground plane is asymmetrical in the edge mount case, which I understand may lead to a directional radiation pattern. Also, the antenna will be partly shadowed by the roof and pillars, which will have its own effect on radation pattern. If the through-hole is a lot better than edge mount, then the question is whether the roof is enough better to accept the significantly higher installation cost, possibility of permanent headliner damage, and increased likelihood of having to replace the whip itself every so often (I don't drive under low clearance often, but that just makes it more likely I'll forget I have an extra meter of antenna on top of the car).
