Michalkun,

If you are going to 'use' a "Balanced FeedLine" (300 Ohm Twin Lead or
450 Ohm Ladder Line) and connect this FeedLine directly into the
radio/receivers HI-Z Terminals then you do not need a BalUn.

However, if you wish to use Coax Cable as a 'feedline' from the
antenna to the radio's LO-Z Antenna Connector; then some form of
matching transformer should be used to get the best results from your
dipole antenna.

A typical half-wave dipole fed with 50 ohm, or even say 75 ohm coax should feed nicely
right into the Lo-Z input on a receiver without a balun of any kind.

Purists may wish to put a 1:1 balun at the feedpoint though.
