PA0RDT Mini-Whip antenna

Update 2018 October: after some water made it into the bottle the antenna has stopped working 🙁

Antenna in a bottle installed on the roof today. Stay tuned for a future web-SDR...

Black electrical tape to keep water, snow, and ice away?

A 2m piece of Thorlabs 25mm aluminium extrusion as antenna-pole.

An article, some theory, some notes on grounding, some comparisons,

There's also a modernized circuit by PA0NHC

Antenna seems to have died due to ingress of water into the bottle - sometime around 2018 October maybe. More and better sealing, silica-gel, or ventilation allowing drying required!
