You are not going to find RG8 with BNC connectors installed at Radio Shack. You would have to get a cable with UHF conectors and UHF/BNC adapters.
The BNC series connector is intended for the smaller diameter cables.
There is one type of BNC made for RG8. The UG-959U is a rare item and costs over $13.
I don't like to see one piece UHF/BNC adapters used on a scanner or portable radio. The most common repair I see with radios with BNC connectors is someone has used heavy cable with an adapter or replaced the stock antenna on a portable with an oversized gain type. The stress on the BNC receptacle breaks the solder connection between the receptacle center pin and the circuit board in the radio or even breaks the board or the radio housing.
A short flexible coax jumper of RG58 should be used with a male BNC on one end and an female UHF on the other to transition from RG8 or heavier cable to a device with a BNC connector.
The BNC is strictly a light duty connector designed primarily for laboratory type use where quick connect/disconnect is important. Yes, you can weatherproof it with tape but it is still a mechanically poor connection that is likely to get noisy eventually.
