The 3158 is a rugged version of the successful 3109 design. The 3158 has larger elements which reduce the VSWR at low frequencies. The rugged construction increases the power handling to 5kW. It is a great antenna for generating higher fields at the 20MHz to 80MHz range.

Frequency Range: 20MHz to 120MHz. The model 3158 biconical antenna is a high power biconical designed for high level immunity. The Antenna can generate 100V/m over a ferrite covered ground at 2m distance per the ISO 11451-2 standard. It can also exceed 100V/m at 1m distance making a good field generating antenna for MIL STD 461F.
