VERTICAL ANTENNA/433.5000

[W0RS]

Any know of an antenna manufacturer that makes a vertical antenna for 433.5mhz? It would need to be no taller then 6ft because it’s going in an attic….

What kind of performance are you looking for? A 1/4 wave ground plane is quite small and inexpensive. Since it will be enclosed in an attic, a properly tuned UHF mobile gain antenna with ground plane kit would give you 5-6 dB of gain at a very affordable cost point.

Whatever antenna you choose, remember that you should feed it with quality coax. Your specific choices should be dictated by run length and TX/RX power levels. I'd probably start with a minimum of LMR 400.
