| Description |
Quite early split-anode magnetron introduced around the mid thirties. It could operate up to about 1400 MHz. Output power ranges from 10 W at 1.2 m to 30 W at 3 m.
- 50 W max power dissipation
- 1.000 V anode voltage
Widely used in several experiments of UHF propagation. Used among the others by Gollin in experimental FM CW radar transmitter around 1937 and by Lowell in 1940 to perfect microwave antenna scanners while waiting for early E1189 samples.
CW10 was developed by E.C.S. Megaw at the GEC Research Laboratories around 1935. Introduced in Wireless World, November 20th 1936.
