Adjustable Dipole Antenna

The 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.

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. The coverage pattern of the antenna is circular, with maximum sensitivity perpendicular to the adjustable elements.

Adjust center frequency

1. Fold arm (element) down to210Antenna Scale. 2. Loosen screws to adjust arm size. 3. Line-up end of arm to center frequency. 4. Tighten screws gently. 5. Extend arm to T position. 6. Repeat on opposite side. o
