Detailed Description

The Valcom compact fan antenna is designed for ship and land applications where space may be lmiited. The VC-NVIS-SL, with its fan loop structure, is optimized for near vertical incident skywave (NVIS) transmissions.

​

The compact fan antenna gives maximum radiation at nearly a 90 degree angle, which can be used for communications at distances between 0 and 1000 KM (620 miles). The VC-NVIS-SL consists of an aluminum mounting/counterpoise frame and a compact aluminum radiating element. The radiating element contains an integral loading reactance and lightning protection.

​

The antenna can be purchased with or without an automatic tuner. The optional tuner provides the capability to tune the antenna between 3 MHz and 18 MHz with a VSWR of less than 2.0:1 in only 2 to 3 seconds.
