"@Vega, as you so clearly indicated -  SWR= Vf + Vr/Vf - Vr  - Where V is VOLTAGE   and NOT 'Variable'..  The term VSWR has NEVER in any Text Book anywhere, ever been referred to as Variable Standing wave Ratio.…"

Vega Tech Group LLC replied to david teles's discussion 433 Mhz antennas for 3Dr radios
"More than likely the dipole antennas you have are not matched to the transmitter. The VSWR(Variable Standing Wave Ratio) is high. This cause a lot of issues, such as poor distance, static and high interference from local RF sources(computers and…"
