[NLRS] MMT 28-144 Transverters?

[Barry Malowanchuk]

They are OK but  not the latest in dynamic range or noise figure.  I have one at home that I am using for a microwave transverter interface with the PA removed and in use with a DEMI low power transverter inside a Flex 1000.  If you can get for reasonable it may be good value
