VSWR Effects
Hi Experts,
Do you know which are the effects of having an antenna with high VSWR?
I just want to know if this issue is reflected by drops, lower coverage or any major problem for the final user.
Thanks in advance!!

Re: VSWR Effects
Dielectric perforation.
Power amp overloaded 'coz power reflected is dissipated as heat.
Copper feeder deteriorated.
Worst radiation performance, not total RF power radiated, a percentage is "lost" heating amplifiers...

Re: VSWR Effects
For sure, VSWR will have all abnormal effects (lower coverage, drops , call failures, handovers failures) as you said.
I experienced this in DT and statistics
Best regards,

Re: VSWR Effects
In LTE ,high values of VSWR result in low throughput due to losses

Re: VSWR Effects
VSWR is (1+|Γ|)/(1-|Γ|)
For example :
VSWR=2 => Return loss =-9.6dB.
lower VSWR is better for antenna.
