SM-3G combines active directional UHF antenna coverage with antenna distribution for multi-receiver wireless microphone systems. It is intended for stages, rental systems, conference venues and fixed installations that need more controlled RF coverage.
Choose SM-3G when several compatible wireless receivers must share a directional antenna pair and the installation needs stronger rejection of RF signals outside the intended coverage area. Confirm the legal frequency band, receiver compatibility, cable length and required number of distributed outputs before ordering.

Is SM-3G a wireless microphone receiver?
No. It is an antenna and RF distribution solution used with compatible wireless microphone receivers.
Why are two frequency ranges shown?
The supplier document states a wide antenna range and a narrower distribution-system range. Confirm the exact current regional version before quotation and shipment.
Can it feed several receivers?
Yes, multi-receiver distribution is the intended use. The exact number of outputs and compatible receiver models must be confirmed for the ordered version.
Send receiver models, channel count, destination market and cable plan for compatibility confirmation and wholesale pricing.
