It appears that our existing Triax multiswitch is about to fail completely.
I've been searching around and the latest versions have a terrestrial active/passive switch. Before I go ahead and order one, could anyone explain what this switch is about please?
I'll be connecting a quad LNB and a terrestrial aerial to it along with eight triplexed wall plates.
The specification seems to indicate a 23db insertion loss (Subscriber loss) in terrestrial passive mode and a 0db insertion loss in active mode.
Active mode user a built in amplifier?
Nortmally A QUAD LNB will not work on a Triax Multiswtich. You need a QUATTRO LNB, unless the Multiswitch explicitly supports QUAD LNB's
Just looked up the datasheet of the triax 5x8 multiswitch.... and to my surprise, it does support QUAD LNBs
When set to PASSIVE it will not amplify the terrestrial input and will NOT filter out 700 Mhz to 860 MHZ
When set to ACTIVE, it will filter the input signals to block 700 MHz to
862 MHz (which are being used by 4G & 5G phone masts AND will amplify teh terrestrial input signals by 23 dB.So it all hinges on whether you already have a mast head amp or not, and what the current freeview signal levels are like and whether you have any problems with phone masts in your area.
Thanks.
No masthead amplifier and the signal on CH55 (746mHz) varies from poor to rotten at times.
Looks like I'll be switching the passive/active switch to active if I swap the multiswitch.
Ch 55 is Com7 which is closing at the end of June so the rotten / poor com 7 will become non-existent!
