Hello everyone I have RFremotech RF-32C - it is 32 channel wireless detonator. In set with device i received basic remote with almost 100m range : https://ibb.co/HVckvJq In 2010 as option was available 200m range remote (with telescope antenna, on below image you can see new version with FSK modulation, old is unavaiable) : https://ibb.co/wpC3pW2 Operating frequency : 433.92 mhz Modulation : Probably ASK (OOK) (new versions runs on FSK). Inside device : https://ibb.co/z8kQH1h Reciever board : https://ibb.co/KFY1zXk Recieve board is probably this (CWC-10) - https://www.alibaba.com/product-detail/CWC10-315MHz-or-433-92MHz-4_1103295522.html Antenna slot at panel : https://ibb.co/26zpg70 Is there any simple and not expensive way to extend range ? I haven't knowledge about radiotechnics. I have idea to install external antenna sma in remote (there is solder pin ANT and 2nd wire to battery GND) : http://www.programatory.com/produkty/anteny/Antena-WIFI-433MHz-3dbi-SMA-86mm.jpg Will it improve the range or only distort signal and give the opposite effect ? Other idea is to improve reciever plate (to buy stronger one). I hope you will help me solve this problem. Greets |
