| ok ovako procitao sam da se umjesto ovih skupih kabela moze upotrijebiti utp kabel. http://www.qsl.net/pa0hoo/helix_wifi/index_eng.htm We got from the surplus of a large project a length of IEEE 802.3 network cable of which we measured the RF losses. The losses were about 0,3 dB per meter at 2400 MHz. As a reference, good RF cable (e.g. aircomplus) is about 0,2 dB per meter. At a cable length of 5 meters, (that was all we needed), the extra losses were 0,5 dB. As we had to bridge just 200 meters, and our antenna was having a relative high gain, we decided to use this cheap (to us) network cable. pa me zanima ima li tko iskustava s time i moze li se to uopce preporuciti. |
