Coupleurs Antennas for 2,4,6
The 1/4 wave of adaptation is calculated = Zo = root of Z1 x Z2 i.e. Zo = root of 50 x 100 = 70.7 ohm , D / d = 3.1 on the abacus formula corrected for the square section example: D = 20 mm and d = 6.5 mm

Duplexer HF-VHF 1,6-150 MHz-UHF 410-480 MHz
Constructing a Six Meter Heliax Notch Filter
All of this started a couple of years ago when an unused Telewave 45 MHz duplexer was discovered at a repeater site. Maybe we could get it to work on six meters
Build a 2-Meter Duplexer
Who has already put a repeater on the air and ask him, What's the toughest technical problem you had with it? He will probably say that obtaining sufficient signal isolation
