Henry Radio makes and sells RF amplifiers for base, repeater, and mobile use in HF (3-30 MHz), Low Band (30-60 MHz), Mid Band (60-88 MHz), FM Broadcast (88-108 MHz), VHF (132-174 MHz), 220 (200-260 MHz) and UHF (400-512 MHz) and at multiple power levels. Henry Radio also sells many components used in their products, as well as some items made by other companies such as Bird wattmeters and slugs, Unidapt kits and cables. This page is mainly concerned with their VHF and UHF amplifier products (30 MHz through 512 MHz).

The photos on the catalog page at the Henry web site implies that all of the rack mount base station / repeater amplifiers are built on heat sinks that are 7 inches high (4 rack units, 17.75cm). Your page maintainer has about 50 of the Henry repeater amplifiers in service at a number of commercial repeater sites, and a large number are on 3 1/2 inch / 8.9 cm) (2 rack units) heat sinks, and has seen other Henry repeater amplifiers on 5 1/4 inch (3 rack units, 13.3 cm) heat sinks. He has also seen special order units that were made for 26 MHz frequencies (the "official" low end is 30 MHz). He's also seen several special units that were two independent UHF amplifiers (5 watts in and 50 watts out) on a single 2U heat sink.

Conversion Articles:

	Converting the Henry Radio C100D10R to C100D30R   by Robert Meister WA1MIK A quick mod allows this UHF amplifier to work with 30 watts input power rather than 5-10 watts.
	Converting the Henry Radio C300C30R to 6 Meters   by John Haserick W1GPO Some variable compression tuning capacitors make all the difference.
	Another Henry C300C30R Amplifier Conversion to 6 meters   by John Haserick W1GPO Replacing transistors, winding some new coils, and adding variable compression tuning capacitors puts this amp onto 53 MHz.
