vswr 50r 75r
Earlier 75 Ohm systems were used. Most probably it was a Russian standerd. Not sure though. But now 50 Ohm has become standard almost in all applications. My question is which system is better?
I feel 75 Ohm is better because easily connected with dipole or yagi antennas. Suitable for edge fed Microstrip as the edge impedances are typically closer to 75 Ohm. Probe feed diameters are become thinner and thus can be usefull for higher frequencies. Power loss due to termination will be smaller. And more ..
What is your opinion?
