The DX Engineering NCC-1 and NCC-2 are excellent phasing boxes for use 
on 80M and below. I'm using one with a pair of VE3DO loops spaced 5/8 
wave on 160M, with feedlines of approximately equal length. Measured 
complex responses for 160, 80, 40, 20, and 10M are in 
http://k9yc.com/VE3DO.pdf The unit is quite well-behaved at 40M and below.
