I installed a low-cost Amazon stubby antenna to clear the box. But... I just got it on the weekend, so I haven't installed the box yet with the new shorter antenna. Visually, looks like it'll be ok. Here's the link to the one I got: https://www.amazon.ca/gp/product/B08G57461L/ref=ppx_yo_dt_b_asin_title_o00_s01?ie=UTF8&psc=1
Here's a pic of it installed: https://imgur.com/a/58Kboy4
