Cat # 2MGPW50 Two meter Advanced Design ground plane for VHF communications. An ideal VHF antenna for base to mobile VHF communications.
Each element and radial is 1/4 wave at 150.00 mHz.
Some trimming may be necessary to lower the operating frequency to mid-band or 146.5 mHz.
The radials may also be trimmed to lower the resonant frequency.
Use a VHF VSWR meter to support antenna tuning.
This antenna is cut a bit oversize to accomodate its use on the VHF commercial and MARs frequencies.
EXAMPLE for 146.5 mHz:
Freq (mhz) 146.5 mhz
Center/Driven Element (inches)
