TV antenna conversion

[Joe G \(Home\)]

Hi All,

I would likke to convert a wide band log periodic etc TV antenna with 300R
or 75R to 50R for my spectrum analyser.

Any pointers to home brew or other made baulns would be appreciated.

Regards
Joseph

try a 75Ohm to 50 Ohm transformer from minicircuits.

I should add, if you are just casually looking at signals, you don't
need the transformer, just connect the 75 Ohm ant to the SA. You only
need the transformer if you are trying to make accurate measurements
(in which case you probably wouldn't be asking this question)
