I have seen from your logs that they work very well! What I meant was that
if you didn't have any or very little noise in the house or in the vicinity
(a cottage with no electricity) and the radio had a high-impedance antenna
connection (like AR7030 with 600 Ohm) would you still use coax and
baluns/matchers? 
	After all every coil, so balun, too causes a bit of signal loss itself. Is
the loss of directivity a bigger reason to use coax & matcher than the loss
of signal strength? 
	And if I anyway choose to use coax/matchers, how long should the coaxes
be, i.e. how far from each other should the antennas' starting points be in
order not to affect each other? I guess 10 metres is not enough? A good 100
metres' coax for five Beverages already costs a lot.
