4 to 5 unused uf.l connections are on the ARRIS Modem router combo model # TG1672G. WHAT ARE THESE USED FOR & CAN EXTERNAL ANTENNAE BE ATTACHED TO THESE UF.L CONNECTIONS TO EXTEND/improve THE WIRELESS SIGNAL? IM NOT ASKING WHAT THE LEGALITIES OF SUCH A MOD ARE & Im also aware of warranty being voided etc.etc. Im just curious if these connections could be used to attach a handful of antennae to & if they would work by simply attaching them? I know it could done it pretty easily but there isnt much info on the specifics of the transmitter(s) &/or if adding these antenna would require anything more than simply attaching them to improve the signal? Once again, Im not asking for a lesson in the legalities of altering the antenna(s). Thank you fornyour time and consideration!
