[QUOTE="Channel Hopper, post: 1064376, member: 175144"] That is not strictly true, the LNB is a downconverter, as long as your receiving device is able to tune outside the usual limits , either by software revision, or a change of front end electronics, then it could conceivably capture and work with signals into the extended bands, above or below the actual specification of the LNB. There are some filters built in to create 'end stops' in coverage, but these vary from model to model and do not cut out the signal completely. Some spectrum analysers on the market have a seamless transition between the UHF and lF bands, making testing outside the usual parameters a doddle, but a switchable converter such as as the Global 250MHz shifters can be used to good effect if there is no access to one.
