What is the easiest way to match a 50 ohm coax with a 75 ohm antenna? I have a Yagi-Udi built with a 2 meter dipole, a reflector, and 3 directors.
The easiest way is to simply connect them without any matching. You'll suffer an additional SWR of 1.5:1 due to the mismatch, but that's well within most transmitter's capability without damage.
The second easiest is to simply employ a tuner.
Neither method will give you the best output power, but they are certainly among the easiest methods of matching.
