Let me first say thanks to everyone for all of their input and information.
I am familiar with the NAB6064A/B heliflex antenna but do not actually have one of those. I do actually own one of the Centurion/Antennex model EXL antennas that Milt mentioned. The only down side is I do not have the tuning information. Maybe if I called them I could acquire that information. I do plan on only using the radio for the 6m amateur band, so I would roughly only be covering three to four MHz. I was hoping to get away with a single antenna for that purpose. Maybe I could incorporate a small telescopic section into my design to compensate for the width of the band. Also, this project is designed to use in a mostly stationary situation, and I was thinking of incorporating a spring or something similar at the base of the antenna to minimize the shock to the antenna connector. It might be best to take this a different direction though, and just utilize the public safety mic with it's antenna connector. That way I could easily attach an expedient antenna for increased range in the field while stationary, and then replace it with a duck type antenna while on the move. ((Yes, I know Motorola never made a low band rubber duck antenna for the PSM. That would be another undertaking) So thanks again for the input. I will let you know what I come up with. Albert KI4ORI
