Tou depan de transmisyon an san fil nan onn elektwomayetik nan frekans lan nan feeder la, diminisyon nan entansite a siyal se diferan. Pou egzanp: frekans nan elektwomayetik: 890 - 920M, diminisyon nan 1 / 2 feeder se: 7.5 - 7 .7dB / 100 mèt. 7 / 8 feeder diminisyon nan apeprè: 4.2 - mèt 4 .5 / 100.

Depending on the wireless transmission of electromagnetic waves in the frequency in the feeder, the attenuation of the signal intensity is different. For example: the electromagnetic frequency: 890 — 920M, attenuation at 1/2 feeder is: 7.5 – 7 .7dB/100 meters. 7/8 feeder attenuation of approximately: 4.2 – 4 .5/100 meters.
