AN/TPS-3
AN/TPS-3 (or SCR-602 T8) is an ancient lightweight early warning radar operating in VHF- and UHF-Band. The development of this radar began in 1942. The origin was a copy of parts of the British Chain Home Low radar. The first radars were exact copies of the British LW prototype. They were designated to SCR-602-T1. There are a number of variants with different carrier frequencies between the 212 MHz of the long-wave British prototype to 1 000 MHz.
The most successful version was the SCR-602 T8 using the triode VT-158 in the transmitter operating at a frequency of about 600 MHz (50 cm wavelength.) This one type got the new american designator AN/TPS-3. The system consists of a console with an A-scope and a PPI-scope and the antenna with its pedestal.
The antenna used with the AN/TPS-3 is a 10-ft parabolic reflector with a horizontal polarized dipole radiator at its focus.
