Hello All
This is the first time I have posted on this list, sorry if I have done it wrong
I would like to use a line powered "cheap and nasty" LNA with an RTL dongle.
This may seem a like stupid question (I will ask it anyway) but will the dongle need protecting from the 18V going down the antenna line. I have seen some diagrams with protection and some without.
If protection is required, has anyone got any suggestions on how I should do it???
Many thanks
Jonathan, M0ZJO
