Unfortunately for me I am the first install by someone who knows very little about Voom.He has assured me that my signal strength of 40 is superb as "only"30 is deemed acceptable by Voom.My S/N ratio is 15.23.Are either of these figures any good?The installer was not aware that the OTA coax lead was to be attached to the Voom receiver and did not even install the Module as he assumed it was the diplexer.Instead he fed the antenna lead directly into the TV! I am not sure if he understands that in order to receive HD on my HD ready Sony 40XBR it has to go through the box.What do you do when you know very little but your installer knows ZIP ???
