To adjust the antenna system, simply release the locking screw and adjust the position of the aluminum housing along the inductance. The inductance itself consists of a PVC pipe core wrapped with tinned copper conductor. For proper contact between the coil and housing, a copper-beryllium spring is utilized.
The MFJ-1661 antenna is greatly enhanced by pairing it with a tripod and radial counterweight setup. It can be effortlessly mounted on field tripods, such as the MFJ-1918 or other similar devices.
Attach a 5-foot vertical whip driver to mount the MFJ-1661 on your vehicle. When mobile, this antenna system can resonate in frequencies ranging from 20 to 6 meters. Once you have parked your car, simply install a 3-meter long vertical emitter. This will enable you to operate within the 6 to 40 meter range.
The MFJ-342 pipe mount facilitates effortless antenna placement on a tripod. For optimal performance, a reliable radial counterweight system must be firmly attached.
