Good day to you all. Am new to RF designs. Presently, am working on a device using RF module for transmitting my signal from TX to RX. Am using the common 315-433MHZ RF module bought from ebay.
My questions are:
- Can I use 1/4 whip antenna for this considering a distance of 60m?
- Can I place the antenna indoor (for both tx and rx), what is the maximum distance it can go if placed indoor?
- If I can't place the antennas indoors, what is the best cable to use to extend the antenna outdoor?
- the SMA connector of the antenna has the inner pin(antenna) and the screw(body). Do I need to ground this body to my circuit ground?
I have executed this project before using normal portable radio receiver antenna but I had so much interference issue.
