I'm building an RFID scanning apparatus, which is going to be attached to a potato harvester, and I'm trying to find a suitable antenna. Because of where said antenna is going to be placed on the harvester, it will have to be extremely rugged. The word rugged in this context means:
It can withstand being bashed against various surfaces: the ground, wooden boxes, hedgerows, etc. (I thought perhaps a "whip" kind of antenna, which could bend rather than break under pressure, might be suitable, but I don't know where to find one.)
It is resistant to damage from wind and rain.
