We Are Not Receiving TV In Our RV
(HSV, AR USA)
How do you check an RV TV Antenna to see if it is bad? How do you check the cable from the RV to the Antenna?
When we use the Scan for channels, it says no signal.
ANSWER: Greetings Jerry thanks for submitting your question on our Ask An RV Question Page.
I will tell you up front that in most cases the reception problem you are having is not due to a bad cable running from your RV's antenna. Without having any test equipment the only way of seeing if the Coax Cable on your antenna is bad is by replacing it. Most RV Antennas use normal Coax Cable. Please follow the steps I outline below.
1. Check the cable connected at the antenna as it may be loose. The cable on your antenna screws on just like the cable on the back of your TV tighten it as needed. Also visibly inspect the cable for any signs of damage, cracks, exposed wires, etc.
2. Now check the cable connecting the antenna to the inside of your RV. Depending on the type of RV antenna you have the cable may be connected to a simple wall plate or a wall plate that has a built in amplifier. Either way you are going to have to unscrew the wall plate to reach the connection/s at the back of wall plate; tighten them as needed.

3. If you find out that you have an amplified wall plate, there may be a tiny switch to turn the amplifier on and off. If this switch is
turned off you will not receive a good signal so make sure that it is on when you are trying to watch the TV. If it was off this could be the reason for no reception.
4. If all the connections were tight and the amplifier was on then you have a choice to make. You can go ahead and install a new cable. If the cable was the problem then you should receive a better signal. This may not solve your overall problem of poor reception of Digital TV Signals on your RV's antenna. Please read the answer I gave to the question below before you decide to install a new cable.How Can We Improve The Digital TV Reception In Our RV?
