Radio aerials on classic MGs cover a range of styles and mounting arrangements appropriate to the era and the bodywork of each application. The original-equipment aerials fitted by BMC, BL and Rover dealers during the production years were typically simple telescopic units mounted on the wing or scuttle area, with the appropriate cable run to the radio set inside the cabin. The Aerials section gathers the period-correct and modern alternatives for owners renewing or upgrading the aerial on their classic MG.
Period-Style Telescopic Aerials
Period-style telescopic aerials use a chromed brass or stainless-steel mast that extends from a chromed base, typically a multi-section design where the upper sections extend out from the lower sections to give the appropriate length for radio reception when in use, and retract back into the base when not needed. The aerial mounts to the bodywork through a single hole, typically about 15 to 20 millimetres diameter, with appropriate sealing washers to prevent water ingress into the mounting hole. The mounting location is typically the front wing on chrome-bumper MGB and Midget applications, the scuttle area on some MGA specifications, or the rear wing on certain dealer-fit configurations. The aerial cable runs from the base of the aerial through the bodywork to the cabin, where it terminates in the appropriate plug for connection to the radio set.
Modern Electric Aerials
Modern electric aerials extend and retract automatically, typically triggered by the radio being switched on or off, or by a dedicated switch on the dashboard. The electric mechanism is housed in a small motor unit inside the wing or the bodywork, with the mast itself rising out of a similar mounting point to the manual telescopic aerial. The benefit is convenience (the aerial extends and retracts without manual operation) and security (the aerial can be left retracted whenever the radio is not in use, reducing the risk of damage from contact with car-wash equipment, vandalism, or careless garage doors). The electric mechanism draws current from the car's electrical system, with the appropriate wiring and supply being part of the installation.
Fixed-Mast and Stubby Modern Aerials
Fixed-mast and stubby aerials cover the modern alternatives for owners who prefer a simpler aerial solution. Fixed-mast aerials are typically shorter than the period telescopic units, typically 200 to 400 millimetres in length, and remain extended permanently. The reception is usually adequate for FM broadcasts in most UK conditions, although the shorter mast length can produce slightly weaker signal pickup compared with a fully-extended telescopic. Stubby aerials are even shorter, typically 50 to 150 millimetres, and provide a more discreet appearance suited to owners who don't want the aerial as a prominent visual feature.
Stubby aerials are typically the choice for owners running modern radios with internal active aerials, where the external aerial is principally cosmetic rather than functional. The technical team is available to advise on the right aerial specification for a specific car and radio installation.
