The SG-303 is a Marine and Mobile Whip HF Antenna System made for rugged and durable HF Radio operation over Land and Sea.
Useful for Ham Radio from 160-6M, CB, Survival Prep, Marine Radio, Military Field Ops, Urban dwellings, and Emergency Communications.
This whip antenna must be used with an antenna coupler (ATU, Remote Tuner) such as the SG-230, 235, etc., or a similarly rated antenna tuner. Radiation is omnidirectional. To be used on a vehicle or boat while in motion up to 60 miles per hour.
The SG-303 is a 9-foot marine and mobile whip antenna for operation from 1.8 to 30MHz. The antenna is supplied in two 50-inch sections and an optional 4-way stainless steel swivel ratchet mount with a reinforced base spring.
Highly recommended as pairs well with the SGC Swivel Ratchet Mount. Tested and re-engineered through years of improvements. Not your low-quality mount.
The loaded frequencies are 13.2 and 22 MHz and the maximum output power is 500W PEP or CW. For Digital modes consider the continuous power rating (or digital mode rating) of your tuning unit (ATU).
When ordered with the mount, the kit includes 3 feet of high voltage wire, a wall feed-thru bushing, and a 3-foot ground strap for coupler grounding.
