Unable to recieve local channels



I’m unable to get channels 4 WRC and 7 WJLA from my location in 20886. I am able to get 5 WTTG and 9 WUSA. The only outside wall with a window is facing 200deg south. The attenna is mounted to the window.

According to the site, they are all broadcasted from the same SSE location 16 to 17 away.

Any suggestions?
