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 (380-512 MHz) and at multiple input and output 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 5w in / 100w out Henry repeater amplifiers in commercial and amateur 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. 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-order units that were two independent UHF amplifiers (5 watts in and 50 watts out) on a single 2RU (3 1/2 inch) heat sink. UHF amplifiers can be special ordered for frequencies as low as 380 MHz.

Model Numbers, Frequency Ranges and Retuning:

Model Number Example: C 30 A 02:
C=Design series (almost all are "C"),
(two or three digit number)=RF Output
A/B/C/D=Frequency band (A=VHF-High-Band, B=220, C=VHF-Low-Band and 6 Meters (30-60 MHz), D=UHF)
02/10/30=input power range (varies slightly with the model and frequency range).

Any Henry amplifier can be returned to the factory for retuning.
Example: Moving a 158 MHz commercial unit to 147 MHz amateur or 463 MHz commercial unit to 452 MHz commercial or 442 or 447 MHz amateur.
The amplifiers are from 4 to 10 MHz wide depending on the model and frequency. Just specify the desired target frequency when returning the unit for retuning.

Product Manuals:

Tempo S30 amplifier 637 KB PDF file donated by Mike WA6ILQ
This is a nominal 30 watt VHF amplifier designed for a l.5watt drive. It was designed to mate with the Tempo Sl handheld (which was introduced about 1978 or 1979), or any l to 5 watt drive exciter that operates in the l44 to l48 MHz (2 meter amateur) band.

Does anyone have any other Henry amplifier manuals, especially low-band and high-power models? If you have paper we can scan and return. Please contact the page maintainer.

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.
