Now you should have two 300 ohm inputs from the outer side and an input GND end in between. If you have an antenna that at a frequency are 200 ohm it will give a 50 ohm impedance at the other side of a 14 balun. On the other side you have an output GND and a 75-ohm output end. You are right it will reduce the signal a little. An ugly 11 balun made from 50 ohm coax and a short lead to the transmitter will allow operation without a transmatch antenna system tuner. Wirewound wideband RF transformers make excellent broadband baluns providing two 90 phas - ing lines to create the 180 shift.
At frequencies where 50 versus 75 Ohm impedance matters it can be quite small.
If youre looking for high-quality and affordable how to make a 75 to 300 ohm matching transformer - youll find the best how to make a 75 to 300 ohm matching transformer at great prices on Joom - from 8 to 17 USD. At frequencies where 50 versus 75 Ohm impedance matters it can be quite small. His results suggest that maybe the other end is a 300 ohm load rather than 75 ohm. On the other side you have an output GND and a 75-ohm output end. Baluns are used with antennas mixers and push-pull amplifiers to create the correct phase relationships and to. Thus a 14 wave of 300 ohm line about 245 feet at 71 mHz will transform the EFHW to near 50 ohms.

You can make a loss matching pad for the 8640 to convert the output to 75 ohms. On the 300 ohm side where the two windings 2 3 connect I think that net should float not connect back to the 75 ohm ground. FWIW the package but not the part is marked Philmore 300-75 OHM Matching Transformer. If you have an antenna that at a frequency are 200 ohm it will give a 50 ohm impedance at the other side of a 14 balun. His results suggest that maybe the other end is a 300 ohm load rather than 75 ohm.
