Default "tuning" in a Freeview digital TV set-top box

You know that business of old, with indoor rabbit ear antenna. Ask someone
to hold the aerial while you monitor the picture and the best position is
with your assistant holding the aerial at an impossible arm's length , in
middle space.

The same with one of these digital boxes. Good external Yaggi and downlead
and the signal bar is 80 to 100 percent on all stationss except two. Moving
the plastic cased box around there is a point , in mid space, where the "no
signal" box disappears and the signal bar goes to 20 to 30 percent on those
channels. Have to be barefoot to work, also wearing a glove nullifies the
effect. Any advice on how to progress, grounded aluminium around the box?
local ghosting effect ? if so why only 2 stations affected out of the 10 or
more on that one multiplexed UHF channel
