Yes but it will basically need two 1/4 wave wires. the ground plane sorta takes place of the second wire. 1/2 wave has advantages but for a portable the 1/4 wave is the most practical.
Is the wire then attached to the plate or the RX device?
The wire is the 6.5 inch antenna. Name: TX_RX_ANT.jpg Views: 708 Size: 73.3 KB
