I have a bat wing on the roof, with a boost inside the coach. It kinda works, but not all that great. Also have a satellite on the roof that does nothing & nobody around here knows anything about it...
If it is a recent batwing, (less than five years), it is the best. To use satellite you need a contract with the Sat company, and a receiver. Use "AntennaPoint" to find what OTA stations should be available in your location. BTW, The booster is actually in the antenna head, box and switch inside is a power supply. Having sait that, there is a true booster that goes inside, which also powers the antenna, and provides additional boost of needed.
