Hopefully, one of you guys and gals knows how these things operate. This attached photo is the receiver module for the remote control accessory to the winch that is mounted onto my car transport trailer. The little green wire that hangs down off of the device is the antenna. This sort of receiver is common on garage door openers. To cut to the chase, my question is, how critical is the length of that sort of antenna to reception performance? It operates on 4.897Mhz Read further only if you want to know the back story and why I would ask such an off-beat question... The trailer often goes months or years between uses and I don't want the winch system left out in the weather all that time. Also, due to space limitations, the trailer's long term parking spot is away from my house so it's a potential theft item. Historically, I remove the winch system after use and keep it in my shop or storage where it gets moved around, bits and pieces get lost and the battery gets used for something else or goes dead for not being on a tender. Whenever I need the trailer, its a huge pain to get it serviceable again. To remedy that headache, I am modifying the trailer to have the entire winch system enclosed in a secure weather tight steel trailer tongue box along with a solar powered battery tender. For security, reliability, weather protection and a clean design, I wanted to mount everything inside the box, but what about that antenna? Inside a steel box, it's not going to be receiving a strong signal from the remote control fob. Solution? Extend the antenna wire so that it can be routed through a grommet to an external location where it can receive a strong signal. But what will that do to reception? Its not coax, it is the antenna, so I'm assuming that its tuned to some degree, but how sensitive are these types of short range low power setups? I'd rather not because it a risk of getting whacked, but an alternative could be to go ahead and mount this one component on the back wall of the box, but laying flat against a steel plate, wouldn't that deteriorate the reception?
