there is no alternative for RG-59 cable You can't get hex crimp connectors for 59 over there- how many do you want?
Can't believe twist-ons are what everybody uses.
Not for when you are splitting satellite signals for a multi multiswitch or a stacked system.Yes, for sat signal distribution you would use at least 2Ghz devices.
Oddly enough, our F-con splitters and combiners here are 2.4GHzGuess it depends on what services are the most common. Here it's CATV which can go up to 1000Mhz so that's why 1000Mhz splitters are available.
Most usual sat installations here wouldn't use splitters at all, might use a multiswitch at most. Only when you get into larger systems will these and other things become necessary so you have to have your sources for these items.
