I understand that IF's are used in TV distribution to down convert for cost and design reasons of filters and amplifiers etc..., but I wondered if there was a limitation with the fact it normally needs to go down coaxial cable?
Therefore; does general coaxial cable have a 'maximum frequency'? as the TV IF range is normally around 950MHz to 2.1GHz but this doesn't carry all of the channels I believe (the set top box must 'request' which channels it wants as signals are polarised).
