RSSI (signal and Quality (packets received transmited) are too low...you need over 15 dbi at least ...try to make a big reflector (wire mesh , chicken coup wire...at least 1 m , put it in the back of your antenna) Router (waterproof) close by the antenna (losing signal on cables)

You are using a Circular polarized antenna and tryin to receive a VERTICAL polarized signal...NO GOOD...and  shifted band frequency too...

YOUR antenna should provide Vertical polarization and be centered at 920 MHZ with a Bandwidth of 80 MHZ (880-960) Yagi Vertical polarized...

Es que en si me gustaría priorizar la antena de disco para la B1 2100mhz porque por el repetidor tri banda que tengo me es muy inestable esa frecuencia y me llega muy poca señal casi siempre se mantiene en 1800mhz y estoy a 8km de la torre 

I would like to prioritize the dish antenna for the B1 2100mhz because due to the tri-band repeater I have, that frequency is very unstable and I get very little signal, it almost always stays at 1800mhz and I am 8km from the tower.

Me gustaría dentro de sus posibilidades este plano para la frecuencia de 2100mhz y como se desempeña con solo 10 discos en vez de 20 si no le es molestia es que no dispongo del equipo y me gustan las publicaciones detalladas que pone sobre cada antena 

 

I would like, within your possibilities, this plan for the 2100MHz frequency and how it works with only 10 discs instead of 20. If it is not a problem for you, it is because I do not have the equipment and I like the detailed publications that you put on each antenna.

La antena BDM-2 está diseñada para uso en exteriores, aunque a menudo se aplica en instalaciones residenciales/no residenciales.

Los expertos recomiendan el uso de la antena BDM-2, como equipo cliente en todos los casos, de construcción de redes inalámbricas de pequeño y mediano alcance.

El original de la antena es con un vibrador cilíndrico de 64 mm de diámetro.

,,,quieres una antena que funcione en 1800 MHz y 2100 MHz...???

Si de ser posible de lo contrario una para2100mhz y otra para 1800mhz con 10 discos en vez de 20 para comparar su funcionamiento y elegir con cuale quedo para la zona donde vivo que la BTS esta a 8km y vivo en una zona rural con varios obstaculos por delante si no es molestia

Ya te respondí lo que no me llegaban las notificaciones si es posible una para la 2100mhz y otra para 1800mhz con 10 discos en ves de 20 y si es muy díficil entonces una que trabaje las dos frecuencias. Gracias por su atención y su tiempo

Aquí en Cuba la conexión es pésima y gracias a sus aportes hacemos las antenas de discos conectando a un dipolo base por inducción porque el otro tema es la falta de electricidad y en michas ocasiones un repetidor no sirve en esos casos
