Topband: Need antenna help

[Artek Manuals]

The first question to ask is what is the operating goal for 160.

1) Local net or rag chew with his buddies.? In that case use the 
existing vertical assuming the AATU can match it is enough . Might have 
to a add lump loading coil at base  to get it the point AATU can deal 
with it . Generally this is a low impedance solution and likely a good 
open frame style relay with 10-20 amp contacts area will be fine

2) Casual worked all states and occasional EU DX especially from NE USA 
. I worked a fair amount of DX years ago using only a 33ft Butternut 
vertical and a KW which for all practical purposes is a simple base 
loaded vertical

3) Is high power involved or is this a  barefoot operation?

4) If he really wants to be heard ( and be able to switch the neighbors 
touch lamps on and off at 25 wpm ..chuckle) then switched in top loading 
wires and 1500W amp is the reality. OR move to the county and put up 
some real antennas.
