Drew, I'm running an FT2900 in my 40 and I opted for a Comet SBB25. It's a great 2M antenna and only $50. About 4' high. I have it mounted on the flat top surface of my PS front fender. This antenna can fold over, so no issues getting it into the garage. I went ahead and just drilled though my fender for the mount. Super sturdy and low profile. I can really get out with the 75 watts of the 2900 and this antenna combo.
