Hi,

I’m hacking a pair of walkie talkies (446MHz) and i was wondering whether bending the antenna (90 degrees to the left, to fit the new case) would affect the range. I don’t think so but i just wanted to make sure.

Also, there will be a 100kHz boost converter right next to it, will this cause any interference? If so, what can i do to prevent (decrease) it?

The helix antenna working in axial mode (which is the antenna of your walkie-talkie) it will work much worse if you bend it from the middle.
If you change its position (without bending) you might get an improvement for some positions.
If you have a noisy DCDC converter near the antenna, the only thing that you can do is to suppress the noise from the source (shielding somehow the converter).
