Try a current choke 'balun' instead of the BL2.
As a temporary antenna I have 25m of twin speaker wire run out from the 
shack under the roof tiles - that's about 7m - and then the remaining 
18m split as a doublet. It hangs at an average height of 5m from a 
couple of trees. The 'feeder' end connects through a current choke on a 
short piece of RG58 to the KAT3 in my K3. The KAT100 has the same 
matching range as the KAT3 and I assume the LC values are the similar.
I have no idea what the loads are but the tuner finds a match on all 
bands 10-80m - but not 160m where the radiation resistance is tiny and 
the common mode choke good enough to render the band effectively dead 
unless I connect just the coax inner.
