Paul,
Is that true about 300 ohm Ribbon?, I thought that us over here in NZ, took our first TV reciever systems, from the UK system?, which meant Huge low-band VHF aerials, and Ribbon cable.
Believe me, Paul, we are still taking out Ribbon from elderly peoples homes, who have just purchased a new digital TV set(for some reason, I've been told, these TV's are louder),and a hearing aid is not required to watch them.
But, with regards to F-connectors, I prefer the crimp type, especially for Outdoor connections, these have a special sealing grease in the rear part and a rubber O-ring in the front part of the plug, where the centre conductor protrudes, these are standard in all of my aerial installations.
