Nominal Impedance

Recommended Posts

Many of the wireles we commonly use are different models of the same manufacturer Comtech. All the specification files I saw about those systems in the manufacturer web shows for the receivers a Nominal Imput Impedance of 75 Ohm ¿¿??

As far as I know all the aerials we are using are 50 Ohm ones. How does the impedance difference in reception affect to the general video quality?

To be honest it makes very little difference on the receiver. No video quality loss at all.

That is less than a 0.2dB RF mismatch loss, so I personally would not worry about it.
