Loosing signal on both 910Mhz and 433Mhz at same time when in LOS within 1KM.

I'm loosing signal on both 910Mhz and 433Mhz at same time when in LOS within 1KM. I'm not sure what my problem is. Maybe it's just that I was in a noisy environment. My flying field is very close to two airports and is basically in town. Maybe it's because my video TX is too strong. Here's my setup:

800 mw 910 MHz video TX with ibcrazy 910 MHz circular polarized antennae
910 MHz video TX with ibcrazy 910 MHz circular polarized antennae
100 mw 433 MHz OpenLRS TX with telemetry disabled with ibcrazy 433 MHz dipole
433 MHz OpenLRS RX with ibcrazy 433 MHz dipole

I was sitting within 10 feet of a low chain link fence today. I was having trouble in all directions though. I was not expecting to have any trouble with my 433 MHz signal. I thought it was possible it might mess with my video TX, but it comes in clear up until I loose both signals.

Sounds like RF environment. I fly at one place that has a spot the flyers call the Bermuda Triangle. A nearby repeater station blows 2.4 & 5.8 freqs. completely away. Several aircraft have gone down in the same spot. Even when I fly through on 433 and 1.3 video the video gets wacked but still flyable.

I'll have to try it out in the country when I get a chance.
