CountyComm AM Ferrite Swivel Antenna – GP-7 SSB

The CountyComm AM Ferrite Swivel Antenna is a spare for the GP-7 SSB.

A Ferrite rod antenna is a small magnetic loop antenna used in AM broadcast transistor radios for medium & long waveband reception and RFID applications. It is designed with a rod or bar made of ferrites and includes a coil wound around the ferrite rod with the help of a variable tuning capacitor in the radio circuitry.

When made with a suitable ferrite core, the antenna gives excellent results over shortwave frequencies. The core helps to concentrate the magnetic field of the radio waves and gives out a stronger signal than a similar-sized air core antenna. Other names for these antennas are ferrod, ferrite rod aerial, or loopstick antenna.

The Ferrite Rod Antenna is ideal for portable applications as it is lightweight & smaller. The antenna is effective for medium & long wave bands, but it is also used in shortwave bands for lower frequencies. Primarily, a ferrite rod antenna is used to receive lower frequency signals between 50hz to 50khz. It operates as transmitting antennas for applications that are suitable with low levels of power & low efficiency.
