The Ultimate Guide to RF Bands: Everything You Need to Know

RF bands span LF (30-300kHz, e.g., NDB navigation) to 5G mmWave (24-100GHz, 20dB/km loss driving small-cell densification). HF (3-30MHz, 10-100m waves) supports global shortwave; GPS L1 (1575MHz) hits 5m accuracy—physics like path loss and antenna size define each band’s role. What Are RF Bands? The entire RF spectrum is officially defined as waves with frequencies […]

6 sources of radio waves

default / Dolph

Radio waves stem from lightning (10-100kHz, peak power 1GW), solar flares (1GHz bursts hit 10¹⁵W), cell towers (800MHz-2.6GHz, 10-40W output), weather radars (X-band 8-12GHz, 1MW pulses), Wi-Fi routers (2.4GHz, 0.1-1W), and thermal emissions (body heat radiates ~0.001W/m² at 10GHz). The Sun and Solar Activity When we think of the Sun, we usually picture the intense

5 Things radio waves and microwaves have in common

default, NEWS / Dolph

Radio waves and microwaves both propagate at 3×10⁸m/s, obey reflection/refraction (e.g., 99% reflect off copper), suffer atmospheric loss (oxygen absorbs 60GHz microwaves like HF radio in ionosphere), and enable comms—Wi-Fi (2.4GHz) or FM (100MHz)—via amplitude/frequency modulation. Same Family, Different Energy They are fundamentally the same type of energy—oscillating electric and magnetic fields—and they both travel

Unlocking the Secrets of GOES Satellite Frequency: Everything You Need to Know

default / dolphmicrowave

GOES satellites use L-band (1690-1710MHz, e.g., GOES-18’s 1698MHz downlink at 12Mbps) and S-band (137.9125MHz telemetry) to relay storm imagery, solar X-rays—frequencies optimized for low interference, enabling real-time weather monitoring across the Americas. What is the GOES Satellite? They are positioned in a geostationary orbit, approximately 35,786 kilometers (22,236 miles) above the Earth’s equator. At this
