I send you Mr Alan like I promise , professional antenna, end feed 1/2 lambda. I send some photo and schematic diagram.

If this work on professional police radio, and 20 MHz low on amateur radio(on my IC-2E) it must be simple work. On the original antenna you have only connector , coil and trimmer capacitor(ceramic), and it is so small dimension. Amaze how possible but work, now I must make connection from original connector to BNC , all antenna is lightweight so I have intention to make another(telescopic)for my hand held radio.

P.S. No need choke

The pipe looks just like a "snow plow flag stick". Whaddayoucallit...

Road office sometimes uses those instead of treetops to mark roadside, curb etc.

Come spring, you can gather it from ditches :)

Where do you get the "Orange" PVC Pipe?

I live in the USA and have never seen it here, but it would be nice to have.

Thank you for the interesting projects.
