For this reason, a good quality outdoor antenna is strongly recommended. The following is a brief explanation of the type of connections that are provided with the various antenna systems. 1. A 75-ohm system is generally a round cable with F-type connector that can easily be attached to a terminal without tools (not supplied). F-type connector 2.
