[ANT] Can I use an external antenna on my product and feed RF from PCB to housing in a coax cable?

Yes, but notice that when you feed the RF through a cable the antenna looses its RF ground plane. So the antenna at the end of the cable must be a dipole antenna!

[ANT]”Is a flexible antenna (a wire) simply soldered close to the RF-Plane sufficient aa antenna – or a perpendicular soldered stiff wire with quarter wavelength over a ground plane leads to the best result?
[ANT] How large must the ground plane be for a monopole whip antenna?
[ANT] “The problem is that that demo kit has a much longer range compared to the design. When we mount their homemade wire antenna onto the demo board the range is like 250 meter in-line with our needs. However on our own design it is only 50m range. Everything else work fine.  Is this an issue on the PCB or an Antenna matching/design issue? “
