As you all have said, the original TP issue is a problem in these 2 area's; of linear; it is basically a radar near them. For instance, where i am at, there is no TI source of almost any type (3.7-4.2) anymore. In the Cities, the new "globes" they hang on the freeway light the ground "up" with close wideband networking in "bands" of circular interference cut next (and they say alongside) into everything that has a ground. This noise is overwhelming the lnbf in low power C and Ku band downconverters at the same bandwidths and makes the meter say "too much noise with me type reception occur's". They need to 1) isolate the direction of these signals and put shields between them (if it will work). Then the carrier portion of the dish and its aim can be the only "gained" signal. In close in area's to the transmitters even tree's and building's are too saturated with these 500-1000-10000 watt placements of "microwaves at band". Vancouver to B'ham in Washington is one area this is the happening m sure it saturates the lnbf also. All of the channel's have that perfect varied strength in the "satellites direction"; so by varying or blocking the nearby boats with 3.7-4.2 (and the cuts on the Titanium) will suffice; not to mention the radar at 4.3 Ghz. which airports rely upon these days (did i say it can remove some of the military anti-radar, but not all). Yes, this causes blipping.
