It was coax for a tv antenna, RG6 if i do recall. After some research its not ideal for ham as you said 50ohm is what the radio expects. So i will be loosing some signal because of the ohm differences.

I still get alot more range compared to my whip antenna.

Im very much a novice in this regard, so please do let me know if there is something im missing!

Thanks for your insight aswell!
