External antenna
Posted: 12 Dec 2017 18:13
I'm wondering if there is something special one should do to attach an external antenna to the Zuno board? Sorry but I cant find any info here or elsewhere.
I have desoldered the original wire antenna and soldered a UF.L connector to the PCB footprint. Then a 1m coax cable to which I have attached a 868Mhz 1/4wave rubber antenna. The reason is not long distance from hub/routing slaves, but I do get a very bad signal inside the metal cupboard in which my electricity switchboard (and my Zuno) will reside. So I made a hole in the top of the metal box, ran a coax from the Zuno out through the hole so that I could locate the external antenna outside the metal cupboard.
Things improved somewhat, but I still get "CanĀ“t detect device" messages frequently. My external antenna is ca 5m from the Vera Plus and 3m from nearest Z-wave device (FGS-223). Is there a capacitor or PCB trace that should be removed, or something added, to better adapt an external antenna?
