rb 433gl + r52hn bad spectrum

hello for all.
i have new r52hn 10~ pcs and rb433gl
i try to use for 2.4 ghz.

but I have problems with the signal spectrum. I use the antenna 12/120 Degrees 14dbi. V / H.
all cards show a similar interference. In this case, the r52n-m cards show a clean spectrum and work well.
