Applications
The Motorola S5415A is an external vehicle-mount RF power booster designed for the Motorola EE3 series of analog and early digital mobile phones — a product family that was prominent in the mid-to-late 1990s when in-vehicle mobile phone installations were common in fleet, commercial, and executive vehicle settings. By routing the phone's RF signal through a higher-power amplifier and connecting to a roof-mounted or glass-mount external antenna, these boosters substantially extended the effective range of the handset, which was especially valuable in rural areas or buildings with poor in-building signal. The S5415A interfaces directly with specific Motorola car kit cradles (SLN3482B, SLN3506A, SLN3500B, SLN3501B, and later versions), making it a drop-in component for those cradle-based vehicle installations. Today these units are sought by collectors of vintage Motorola mobile phone equipment, by hobbyists restoring period vehicle communication systems, and occasionally by technicians maintaining legacy fleet communication infrastructure.
This Motorola S5415A 3-Watt EE3 Cell Phone Booster has been inspected and is in good condition. The black aluminum enclosure shows minor surface scuffs and light wear consistent with prior use, but there is no cracking or significant damage. The D-sub connector, SMA antenna port, and rear RJ-type port all appear intact and undamaged. Please view our photo set and contact us if you have any questions. Please note: We have multiple units in stock — yours may not be the one shown in the photos, however, it will be similar in condition and function.
