Magnavox Audio Players & Recorders - Recent Questions, Troubleshooting & Support
Where the antenna of Magnavox Solid State Radio is located? I would like to install one on my radio that I just got.
I don't know but will take a guess - I expect the radio is a vintage am/fm transistor radio. The am antenna is likely to be a ferrite rod tuned directional type that will be inside the cabinet.
The fm antenna might be a single core wire that dangles from the set in the way commonly used by many fm radio-alarm clock-radios. This performs the same function as the single telescopic antenna of portable radios without the cost and similarly is connected internally to the first rf stage. Sometimes due to age, mishandling or ignorance the dangling wire is lost or cut off.
A higher quality table radio (not designed to be portable) is equipped with a facility to connect a 300 ohm balanced antenna, a 75 ohm fm antenna or both.
The 300 ohm type connects to a pair of screws accessible at the rear without removing any covers and is usually an indoor type. The 75 ohm type plugs in with a standard coax plug and could be either an indoor type or an outdoor type.
A matching transformer is available to use a 75 ohm antenna with a 300 ohm input. The 300 ohm type is highly directional in horizontally polarised signal areas and is not always convenient to use.
