[BC] 3 dB improvement...

[Burt I. Weiner]

Most UHF TV receiver front ends are pretty basic.  Some currently 
manufactured set still go directly into a mixer without a RF stage 
ahead of the mixer.  Low noise, wide dynamic range devices for the 
UHF frequencies are pretty inexpensive.  Consider the front end of 
cell phones at 900+ MHz.  Throw away stuffs.  I would never suggest a 
decent antenna as most consumers just want to plug it in, twiddle the 
loop antenna and watch - a fact of life.  A 3 dB front end 
improvement would actually be pretty simple since this would be the 
first 3 dB and not the last 3 dB.
