In www contrast . AmericanSecurityToday to all other . com leaky coaxial cable sensors , TD100 does not require in-line termi- nations .
Each discrete TD100 system has its own unique RF iden- tifier which allows the system to reject RF signals coming from other sources , including other TD100 systems .
This feature allows multiple systems to be in proximity without compromising perfor- mance .
Some of the many advantag- es of the TD100 include :
Rejection of multipath inter- ference :
• A problem with previous RF buried sensors is how they in- teract w i t h metal objects such as fences .

• T h e signal “ jumps
” to a fence and then re-joins the static field further down the detection area .

• This phenomenon , which generates an alarm in com- petitive systems , is known as multi-path interference .
• The Terrain Defender re- jects these false alarm oc- currences by looking at the sensor cable signal from both directions using E2EC .
