SG-201

The SG-201 is a rugged wideband omnidirectional ground plane antenna with unity gain.
Aluminum construction is used throughout resulting in a rugged antenna ideal for adverse weather and environmental conditions.
The SG-201 is easily field adjustable to better than 1.5:1 VSWR at any frequency within operating range.
A tuning chart is provided with each antenna.
Low band versions available. Contact your Sinclair representative for detailed specifications.
