 |

Hi, First let me introduce myself as I'm new here and to antennas. I'm a retired electronics teacher but still doing some supply work as there is a shortage of specialised STEM subject teachers in the UK. My interests these days are mostly in building model live steam locos in 16mm scale which has nothing whatsoever to do with antennas.
However I love making things and am still very active in my eighth decade. I have a holiday home in Brittany and stay there for a few months a year. It is in a very remote rural hamlet (3 properties) and I am pretty well cut off from the internet. This last year there have been developments in the area with cell mast upgrade and some 4G coverage and I can get a 4G signal enabling me to set up a hot spot but the bandwidth and signal strength is poor and the signal can fail at times. My wife can work from home using broadband in the UK but not in France and she would love to be able to spend more time there and be able to work.
In order to improve the signal (and gain some brownie points) I intend to build a Yagi Uda antenna to feed a 4G modem. My nearest mast uses a downlink frequency of 857mHz and uplink of 816mHz. I have a yagi design programme and the metalwork is no problem but my real question is, as a novice, is what frequency should I aim for - 816 or 857 or will a yagi designed for the middle of those (say 837mHz) work.
I really would be grateful for any advice. Thanks in advance.

thanks for that advice, it was as I suspected. Also the link to the dipole page is incredibly useful. I will experiment and report the results.

| Another question I failed to ask, should the dipole be bonded to the beam or insulated from it? I have seen both methods on different web sites. |
