You can get a push on adapter that screws to the normal coax connector at most good electronic suppliers, no need to cut off the screw on connection. I picked mine up at "Radio Shack", trying to keep them in business. I looked at the big box stores and didn't find any but where you are they may have them. Just ask for a push on coax adapter. Places like Fry's most certainly would have them. I searched Ebay and saw them for about $1 each. Just search "push on coax adapter".
A lot easier to hook up coax lines.
