The Lectrosonics SNA600 antenna is a versatile tool for use with wireless microphone receivers or IFB transmitters. The center frequency of its 100 MHz bandwidth is tunable from 550 to 800 MHz. The frequency is set by adjusting the dipole elements using the scale printed on the body of the antenna. The elements fold for storage. Features SWR less than 2:1 over 100 MHz bandwidth Adjustable elements tune center frequency from 550 to 800 MHz 3/8” x 16 threaded socket and stud with mounting strap included Built in balun matched to 50 ohm BNCconnector Folds for storage Can be used with antenna power enabled on the receiver or multicoupler The SNA600a antenna is a versatile tool for use with wireless microphone receivers or IFB transmitters. The center frequency of its 100 MHz bandwidth is tunable from 550 to 800 MHz; however, the roll-off above and below this band is gradual. The SNA600a measures lower than a 2:1 SWR (Standing Wave Ratio) from 465 MHz to 850 MHz when the antenna arms are fully extended. The frequency is set by adjusting the dipole elements (arms) using the scale printed on the body of the antenna. The elements fold for storage.The body of the antenna is made of fiberglass circuit board material. Nomenclature is printed in copper on the board with a black solder mask to provide excellent visual contrast. Copper traces on the circuit board form a balun for an ideal match to a 50 ohm line via a standard BNC connector. Can be used with antenna power enabled on the connected receiver or multicoupler. Adjust center frequency Fold arm (element) down to Antenna Scale. Loosen screws to adjust arm size. Line-up end of arm to center frequency. Tighten screws gently. Extend arm to T position.
