 SG301The
SG301 is
a versatile antenna ideal for use where broadband, unity gain, omnidirectional coverage is
needed. It covers a 20 MHz bandwidth without adjustment. SG-317 The SG-317 series is a tunable, low-cost 3 dBd gain omnidirectional base station antenna for the 406-420 or 450-512 MHz frequency range. These extremely versatile antennas may be field adjusted to resonance within a 20 MHz bandwidth. A frequency adjustment chart is supplied with each antenna. Ideal for leased system service because of the field adjustment capability, the SG-317 is also a good choice to stock for re-use or re-sale. |
