Got my UV-5 Today! I have to say that this thing in big!

Consider this before you buy one:
Overall Length = 7.1/2"
The Cord and Strain Relief will add another 1.1/2" to the length with the cord bent 90 Deg.
The cap is 3" dia.
The Body is 2.37" dia.
The unit comes with nice 3/4" barbs and universal-cut-to-fit .355 / .486 / .637" barbs. Note that the sizes will not be tight on 3/8" and 1/2" hose. The barbs use a flanged sealing surface with a neoprene? :shrug: gasket.
The unit's cord has a "Wall Wart" which is an octagon 2.1/4" across the flats and 2.34" long. The UV-5 is made in the Netherlands and there are markings on it:
MCT Transformatoren GmbH
StSF 5-63-0499 U
Lamp 5W
120V 60 Hz 0,18A
(lambda symbol) 0,45

The bulb is a Philips PL-S 5W TUV UV-C Type.
