I am working on Tx Rx based on HT640 and HT648 on 434Mhz with ASK Module. I am in search of a good compatible antenna for the same because I always face problem of range while operaing it. Please suggest me something!!! Thank you...
We used radio antenna, which are very cheap and we can adjust the height of the antenna to our wish..... I got a very good and considerable length coverage with that too.......
