Some radios have an abnormally long SMA post on them which leaves a gap between the radio and the antenna. You can add on a spacer to fill that gap if your radio has that issue.

Connector: SMA Male

Please look at the images to make sure you have the correct connector! We usually have two or three orders per month that are sent back because the customer mixed up male vs female (the gender is determined by the center conductor, not by the threads!).

These are hand-made, ultra lightweight, and nearly indestructible antennas which outperform the stock antenna your handheld radio came with by a significant margin. Originally designed to use as a fundraiser for a youth group, sales from these remarkable antennas now provide funding for HamStudy, ExamTools, and other initiatives which help support the Amateur Radio community.

All Signal Sticks are hand made; if you are looking for perfection in aesthetics then these may not be for you, but our design is continually evolving in order to provide better looking, better functioning, and above all more durable antennas.

    Excellent order in accuracy and speed. I was told it may be about 2 weeks for shipping, but I’ve received the antenna in about a week.

    The Signal Stick is pulling in RX that the other aftermarket antenna I was using couldn’t find. It’s well made and it’s a bit taller, thinner and lighter than I was expecting…that’s actually a good thing in my opinion. I chose the blue dual bander. The blue makes it stand out but not in an unpleasant manner.

    Overall EXCELLENT!
