Yes,
all stations of interest are about 40°. DC 4 miles away & Baltimore 40 miles. No distribution amp needed for 1 TV, but as soon as even a 2 way splitter is added, 2 of the weakest Balt UHF's disappear. The 3414 works much better than anything else tried which involved a passive splitter. The marginal stations show no signs of intermod & actually a bit better reading on the signal strength meter. No attenuation other than one HLSJ to trap screeching FM & analog channel 6 only 1/2 mile away.
