Hi All,
I have a 900MHz radio system and I want extend 50ohm coax cable from 3m to
20metres.
(well.... I mean - replace the 3m with a complete 20metre section with
proper termination coax connectors etc)
What losses and reflections should I watch out for?
Eg if the cable is a multiple of the 900Mhz wave length or 1/4 wave length
etc... is there refection effects.
Obviously there will be losses rated in db per metre (foot) etc....
What else should I pay attention to?
** PS the antenna is std 50ohm termination and the transmitter is 50ohm
termination and the cable is 50ohm coax style - already.
** Transmission is spreadspecturm **
???? Is this the right NG? If not - please advise which NGs might be more
appropriate.
Thanks in advance.
