LuisT Posted December 11, 2020 Report Share Posted December 11, 2020 Hello everybody, i have a quick question for the following configuration : WISYCOM LFA Antenna > coax cable 25m > PSC 6 Pack > Lectrosonics SRC's + Audio Limited A10. I know that the loss of the 25m cable is 3,68db (i asked the rental place). What i don't know and can't find in the manuals is the loss of the 6 Pack. I see there is a 0,8db noise figure but the manual does not mention any loss. I red that the wisycom LFA Antenna has a 7dBi gain typical. My question is, how much gain would i need to set the LFA to have a "flat" gain structure equal to 0. Thanks a lot Quote Link to comment Share on other sites More sharing options...
Constantin Posted December 11, 2020 Report Share Posted December 11, 2020 3.68dB. The Sixpack doesn’t have any loss. Quote Link to comment Share on other sites More sharing options...
LuisT Posted December 12, 2020 Author Report Share Posted December 12, 2020 Thanks. And what about the 7dbi of the LFA antenna? Should i had this into the count? Or it's just +7db when the Tx is fully in axis of the cardioid pattern of the LPDA? Thanks Quote Link to comment Share on other sites More sharing options...
Soundwil Posted December 12, 2020 Report Share Posted December 12, 2020 The 'Gain' of the LFAs is a measurement of the noise floor as compared with an omni antenna is my understanding , and not a type of gain you should be including in your calculations. *Larry explained it in a post here few months ago or possibly longer, cannot find it sorry.
