Signal loss, or attenuation, is the loss of energy experienced by radiofrequency waves as they travel through a medium. The loss in energy results in a corresponding loss in how well the signal, sent from the transmitter, is relayed to the receiver.
When we’re talking about cable loss specifically, we’re talking about signal loss experienced by RF (radiofrequency) waves as they pass through an RF cable, also known as coax/coaxial cable.
2.1Â Â Â Â Â Â Does length of coaxial cable affect signal?
Yes, the greater the length of coax cable you use, the more signal loss you will experience. The higher the frequency the higher the losses when compared to lower frequencies over the same cable length.
2.2Â Â Â Â What types of cables do we mainly use at Inteto Connect?
HDF/LMR cable are registered names that refer to various gauges or diameter, i.e., 195=5.5mm, 240=6mm, 400=10,29mm.
- Closed-cell polyethylene dielectric low loss flexible cable.
- HDF cable is best used for Wi-Fi frequencies in the 2.8 & 5-6GHz ranges.
LMR cable
- Low loss, flexible broadband cable often used in WISP and other wireless applications.
2.3Â Â Â Â What type of cables do we prefer for installations?
We prefer using LMR400 and LMR240 cable.
LMR400 is a thick black cable and not very flexible.
In difficult installations we use LMR240 as the losses are less than that of 195. For highly demanding outdoor installations we use Succofeed 13mm.
