Here is a good one (of course this is happening when we are 3 hours away from our shop) - using both an aim and a birdog meter we can get a phase one (legacy reflector) to lock onto 101. when we use a slimline neither meter will lock. we have tried two sl5 and sl3 lnbs (we cannot use swm for this install because we are going to go into a swm16 switch because we need 11 tuners). the jpole is plumb. we have aimed hundreds of slimlines. we have tried all combinations of azimuth, elevation, and skew. the LOS is perfect. we are STUMPED! any ideas out there?
