Can I use a 1.2-1.4GHz antenna?

[Flutter 0]

I just got a 1.2-1.4GHz antenna and I wonder if I can modify it to use it for my 2.4GHz system?

Also, my Graupner radio (tx )has messed up and I need to buy a new one. Which radio do you recomend when range is the main issue?

... I can modify it to use it for my 2.4GHz system?

Modifying it for 2.4Ghz operation would involve reducing (scaling) the antenna's elements to shorter lengths. The scaling depends on the antenna's construction and design.

The main contributor to range is the Rx's design. Not all are created equal. Stick with a name brand and check around to see if the model you are interested in has had any reported issues. For after-market Rx's, both Berg and FMA have good reputations.
