Check the listing for details. UnRS-200 Amplifier RF Antenna relay 120Vdc system for Heathkit SB200 high speed. Condition: New. Listed at 79.00 USD. This 120V dc replacement relay system easily fits the SB200 (and available for other 120V dc) amplifiers. Please read the instructions and look at the pictures. The switching time is about 7mS, nearly twice as fast as the OEM relay. It is also much quieter. This relay system is electronically sequenced. The timing is shown in pictures. There may be a slight appearance change as we switch to a revised board, but electrically and mechanically it remains functionally the same. We also have RF antenna relays for other common RF amplifiers.
