¹ See specifications on product page for details.
² Ideal installation position for all SGC couplers is as close to antenna feed point as possible.
³ Not recommended for outside installation - requires additional protection.
* All SGC couplers require only RF and DC power(not required for SG-211). SGC cables are required for additional features only.
