I just received a longer antenna that I ordered off of ebay. It's 13", so it is about twice as tall. The best part is that it came with an adapter that screws right into our bikes. I thought I was going to have to do some rigging.

I haven't tested it in real life, just in the garage. I couldn't tell any difference, but I always have great reception in the garage.

I ordered it because lately I could only get 1 good quality station, and I live in town (Albuquerque). I removed my old antenna to check the thread size, and then reinstalled it and ordered this replacement. Well, next time I went out, all six of my presets worked pretty darn well (with the OEM antenna).

So we might want to remove and reinstall our antennas once in a while for better reception. If you want to try this $8 antenna that fits, here is one link (others sell the same thing). No affiliation, etc. BTW, it is pretty darn flexible (wimpy). Don't know if that is a good thing or not.
