Clip on Dipole Ch. 38 Antenna
Here's a nice clip on half wave dipole centred on Channel 38 606-614 MHz.
The upper element is a whip and the lower one is helical so the overall height is only 185mm.
The clip is a bit bigger than it needs to be to fix on to your bag or harness but on the other hand it will go on to a door or bar up to about 42mm wide.
This one has 1m of low loss cable with an SMA connector but we also have BNC and 3m cable versions.
