When a satellite installation technician handles R-410A refrigerant in an integrated HVAC-satellite equipment shelter, which EPA regulation applies?
Answer: EPA Section 608 of the Clean Air Act — refrigerant handling certification required
EPA Section 608 requires certified technicians to handle refrigerants, including R-410A, to prevent venting and ensure proper recovery during service.
Under FCC rules, what is the 'interference temperature' concept introduced to manage spectrum use in unlicensed bands?
Answer: A metric defining the maximum RF noise level a receiver can tolerate before performance degrades
Interference temperature is an FCC concept quantifying the maximum additional RF noise a receiver can tolerate, intended to enable more flexible spectrum sharing.
A satellite dish is installed on a residential property. The homeowner's HOA attempts to prohibit the installation. Which FCC rule protects the subscriber's right to install the dish?
Answer: FCC OTARD Rule (Over-the-Air Reception Devices) — 47 CFR Section 1.4000
The FCC's OTARD Rule (47 CFR 1.4000) prohibits restrictions that impair a person's ability to receive video programming via satellite dish or antenna on property they own or control.
What safety hazard does a pressurized waveguide system on a high-power satellite uplink station present to maintenance personnel?
Answer: Risk of sudden decompression injury if pressurized with dry nitrogen and fittings are improperly removed
Pressurized waveguides filled with dry nitrogen can cause sudden decompression and injury if fittings are removed without first safely venting the system.
Which type of license authorizes a company to operate a constellation of non-geostationary (NGSO) satellites providing broadband service in the US?
Answer: FCC Part 25 space station license for NGSO systems
NGSO satellite constellations providing broadband require FCC Part 25 space station licenses, which include technical parameters, coordination requirements, and milestone obligations.
What is the primary safety concern when a satellite dish is installed on a roof and the coaxial cable enters the building through a drilled hole?
Answer: Fire spread through the penetration if not properly fire-stopped per NEC and local building codes
Cable penetrations through fire-rated walls or floors must be fire-stopped with approved materials to prevent fire and smoke from spreading between building compartments.
Under what condition does the FCC allow a licensed satellite earth station to increase power above its normal authorized level?
Answer: Only under a filed Special Temporary Authority (STA) or under an automatic uplink power control provision explicitly authorized in the license
Power increases above licensed levels require either an FCC STA or must be within an automatic uplink power control range explicitly authorized in the earth station's license.
