Brick walls have to be unrealistically thick to be useful . Other materials, such as windows and drywall, are essentially fully transparent to radio waves. Reinforcing a concrete wall with steel rebar did not really improve the shielding, at least at the standard grid sizes.

In line-of-sight communication airborne elements such as rain, fog and snow can all affect communication quality. Of these weather conditions, rain has the greatest effect on VHF data transmission .

Read moreWhat factor affects the effectiveness of VHF communication?
A longer wavelength , which corresponds to a lower frequency, as a general rule lets a radio signal travel a greater distance. Lower frequencies or longer wavelengths also have greater penetrating power.10 Eki 2016
Read moreWhat 5 factors that could affect the range of radio equipment?
Key Points. The key factors affecting communication range are: antenna, obstructions, signal strength (wattage), and signal type .
Read moreWhat is the range of a VHF radio?
Your VHF radio is intended mainly for short range communications, generally 5-10 miles , and at least 20 miles to a USCG station. To communicate at longer ranges, you will normally need a satellite telephone or an MF/HF marine radiotelephone.
