    SA-13U ANTENNA SWITCH
    SA-13U ANTENNA SWITCH. Made in USA. Used in B29 bombers in WWII and worked with the ART-13 airborne transmitter. Normally used with a trailing antenna.
    WWII vintage. This is a high-power 2-pole double-throw RF knife switch. Made in USA. Used in airborne bombers for transmitters. Excellent for use in high power ladder line transmission systems. This is a very high quality military grade switch. It has large 1"x1"x2.5" H rectangular porcelain insulators for supporting each of the heavy duty switch contacts. The switch outline dimensions are 4.0" Wx8.0" L. The overall height when the switch is in the closed position is about 4". Perfect for grounding 450 or 600 ohm open wire transmission lines when not in use, or for switching a common transmission line of two different antennas. This type of switch (and of this quality) is now fairly scarce and hard to find. Will be carefully boxed for safe shipment.
    Great shape. Non smoke environment. Condition is "Used". WELL BOXED FOR SAFE SHIPMENT.
