For an external antenna, I’m currently using a cheap little thing that I got off Amazon for $25. I’m looking to get something better. It has been suggested that I look at Comet or Diamond branded antennas. At minimum, it has to be dual band (2m / 70 cm) mag mount vertical whip. I have a maximum height of about 55″ where I want to put it so proabably enough space for a half wave. I would consider a tri-band for future expansion. Does anybody have any thoughts on something that would be good, but not ridiculously expensive?
