Hi, I'm unsure about this because I know antenna placement can be a bit complicated. I understand the length calculation in open space, but the metal case confuses the issue a bit.
I have a RC radio receiver that is to be mounted in an aluminum box. The antenna can be mounted on the outside of the case. I only need about 1" of wire to make it from the mounting point of the receiver to the outside of the box. It's a 2.4GHz radio system, the transmitter is a Flysky FS-T6, and the receiver is the corresponding R6B.
Questions:
Is mounting the antenna sticking straight up at 90 degrees from the aluminum surface going to cause any problems with picking up the signal? I'm not sure if it would hurt or maybe help.
When calculating the length of the antenna, I don't count the part inside the box right?
When you have an extension wire to an antenna, what prevents that from counting as part of the antenna length? I've seen several systems where you have this precise antenna and then a 1-meter extension cable. It seems like the electrons wouldn't care where we say the antenna begins and the extension cable ends. Is it that the extension is shielded? I'm thinking it is, and thus the part of my wire inside the box would also not count, but this is just my best guess.
Since the wire coming from my receiver is meant to be an antenna can I use it to go to the bulkhead where the new antenna enters the box, or should I replace it with a shielded cable that is better suited to extend an antenna?
Finally, is there any reason a 2.4GHz antenna with a plastic housing that is designed for 2.4GHz wifi wouldn't work? It seems like it would be ideal.
Thanks!
