(2) Passive Dipole antennas to add reliable range to your receivers that may typically have whip antennas. These are a great add on for wireless hop transmitters, IFB transmitters or even talent receivers. Great for tabletop, cart work or also for mobile bag work with an included Betso Bag Holder. These take bnc input and do not require any power or RF distribution device. You can go straight out of a receiver and into the BNC input on this antennas to carry audio signals farther. These antennas are a noticeably helpful upgrade from stock antennas but don't expect as much range as you would from active sharkfin antennas which I also have available for rent.
