[TowerTalk] Reflector in the back of shunt tower for 160m

[Ignacy Misztal]

I am trying to get some gain on 160m where currently I have a shunt fed
100m tower. It works well but is not spectacular.

I modeled a reflector some 100 ft away from the tower. Either as inv L with
one elevated radial or T with two elevated counterpoises. EZNEC shows up to
4 dB gain as a reflector and up to 3 dB as a director. Is this realistic?
Has anybody done anything like that?
