<div>Máte nekdo zkusenost s pasivní retranlaci gsm900
signalu z anteny vně auta kabelem 5m (standardni fme) k
mobilnímu telefonu uvnitř auta? </div>

<div>Rekneme tak 3-5mm k antene uvnitř telefonu.</div>

Jinymi slovy navazete na tu antenu mobilu kapacitne tu
retranslacni...<br>
Pak se to bude chovat podobne, jakoby mel ten mobil konektor
pro antenu a tu jste pripojil naprimo. Pravda muze to byt o
3-10 dB horsi, ta kapacitni vazba nebude 100 procent.<br>
Ale vhodnym zvolenim anteny a pri znalosti koncepce vf
antennich obvodu v telefonu ( kde je antena umistena ) lze ta
vazba udelat dobre.<br>

Koncepci prave neznam ani teorii a 10 dB to uz je docela hodne ne
- 3 nasobne snizeni?</blockquote>
<br>
Ano, ale oproti utlumu v kabine auta je to stale velmi dobre....<br>

Ne to je "indoor" antena z vymontovana z krytu. Pouzivam ji prave na
vazbu pri mereni GSM signalu pomoci ext. anteny, protoze dnesni
mobily nemaj ant. konektor.<br>
Gumickama prichycena k zadni strane mobilu - funguje to vytecne.
Samotna antena nestoji za moc, nimene nalepena na mobil dokaze
"odsat" energii. Dle mereni je tam cca 3-4 dB,<br>
pokud pocitam, ze mobil umi pri zahajeni hovoru na GSM900 pep=2W.
Mereno na FSH analyzeru s utlumakem 30dB.<br>
<br>
Podobnou pouzivaji PMR-kari vazbu na antene , protoze se nesmi
zasahovat do konstrukce a jinak neni mozno antenu pripojit:<br>
