If I want to move the LTE antenna outside using an SMA extension, do I have to attach two antennas to the façade or is only the "Mobile MAIN antenna connector" sufficient? If so, how far apart should the two antennas be mounted?

Question

Accepted Answer

I'm using the RUT240 in a slight valley hollow and was having trouble getting 4G. With an antenna on the roof it works very well.
I used the Delock model LTE/HSPA/GSM antenna, SMA connector ([Delock LTE/HSPA/GSM antenna, SMA connector (mobile phone antenna)](https://www.digitec.ch/fr/s1/product/delock-antenne-ltehspagsm-connecteur-sma-antenne-de-telephone-portable-accessoires-reseau-5837070?ip=Antenne+LTE)) + SMA cable.

I was planning to do exactly the same thing. It worked fine for me with this antenna.
