I am designing a portable antenna with a radiating element and a balun that are not close to each other.
The impedance has been designed to be close to
So I will feed the antenna with a twisted pair of enameled copper that should be close to
Q: I was wondering however how to expose the balanced terminals on the balun enclosure so that they should be close to each other in order not to increase impedance.
- An obvious choice would be a
75 ohmTwinax socket and fitting the custom twisted pair to a Twinax male connector, but these connectors are expensive.
Q: Any idea of what kind of terminals I could use, with limited separation while maintaining sufficient mechanical clearance to avoid shorting the terminals?
(That's why I am reluctant to use spade connectors that could rotate inadvertently). I thought of small banana plugs or RCA connectors. Any other idea ?
- It will handle limited power (
