Default TVI/ W3EDP question

Hi all,

ive been having a bit of a TVI problem with a neighbour whos receiving set
up isnt up to scratch ( Receives me great though and seems to transmit line
timebase sound very nicely too)

Anyhow I tried an experiment using an end fed wire the W3EDP - 85 feet of
wire tuned against a 17 feet counterpoise and said neighbours tv went nuts.
I was feeding the wire into the shack and using a tuner at the window frame
with the counterpoise dropped out the window from the second floor- dangling
with no connection to anything. Now on taking away the counterpoise and
adding a much longer counterpoise which runs underground the interference
problem cleared up.

Can someone explain to me exactly what was going wrong- was the counterpoise
radiating like mad with no path to ground?.

Also can someone suggest some simple antennas which work well against TVI?.
