Hi all,
I am new to the world of RF but would like to understand more so please have patience.
Firstly, can you explain to me how to digest and understand the information regarding dB, dBuV and dBIM values from the attached specs of an old TV FM antenna.
E.g
what values are considered normal as per todays standards?
what effect would be observed if a certain value is increased or decreased?
I’m familiar with impedance in terms of normal electrical circuits but in this case what does it mean?
Secondly, I would like to get an RF Analyzer in which I could connect the antenna in question to see what signal strength and frequencies are actually being received. I would also like the Analyzer to be able to tell me if there is RF interference around certain devices or areas of the vessel.
would I need a bunch of different types of antennas and attach them to the Analyzer then just test the spectrum for the given antenna at the location I wish to test?
how would I go about choosing an Analyzer that could fulfill my needs? For example that wouldn’t be damaged by connecting the TV FM antenna?
sorry for all the novice questions but I’m a mechanical engineer that’s been given the responsibilities of an electrical/AV/IT engineer and unfortunately for me fault finding RF frequencies falls under my responsibility now.
