Kenmore, for years I used a spectrum analyser to align my dish. When that stopped working I looked for a modern device with a fast refresh rate for the spectrum display. I settled on a Promax HD Ranger Eco. Even with the whole bandwidth displayed from the LNB, the refresh rate is good for dish alignment. In addition to the spectrum analyser function this device will lock and display the contents of a mux. Mine works for DVB-T, DVB-T2, DVB-S and DVB-S2. Mine cost about £1000 bought direct from a supplier in Spain. Check
PROMAX for info on their current offerings. SimonE
