Step 4: Make/attach antenna reflector

Take your piece of cardboard (approximately 2'X 3' in size) and cover one side in aluminum foil or some other metallic covering  A heavy coating of spray mount adhesive will hold the aluminum foil in place on the cardboard.

Using some of the same screws you used to to attach the wire lacing/"Vs" to the frontside of the board, attach the cardboard reflector to the backside of the board, with the aluminum foil facing towards the antenna.
