50 ohms is a compromise for loss and power handling. 30 ohms is the ideal impedance for power handling, 77 ohms for loss, hence the use of 75 ohm coax for television and other applications. For receive only setups, 75 ohm RG-6 is often your best bet for coax cable. It's inexpensive, low loss, easy to find and work with. Even for many transmitting applications, it works OK.
