Talk to KD6R, who uses one in a surplus (TACAN?) cavity on 432MHz.
Many years ago K2CBA published a HB design for 432 in the 432MHz and
above EME Newsletter (K2UYH). He built his own socket using brass
plates, fingerstock and Teflon sheet.
In the right RF circuit, the 7213 will give a comfortable 1.5kW out on
432MHz, so you can draw your own conclusions about the lower bands!
