Mphamvu yogwiritsira ntchito zolumikizira za RF coaxial idzachepa pamene ma frequency a chizindikiro akuwonjezeka. Kusintha kwa ma frequency a chizindikiro chotumizira mwachindunji kumabweretsa kusintha kwa kutayika ndi kuchuluka kwa mafunde oyima pamagetsi, zomwe zimakhudza mphamvu yotumizira ndi zotsatira za khungu. Mwachitsanzo, mphamvu yogwiritsira ntchito cholumikizira cha SMA pa 2GHz ndi pafupifupi 500W, ndipo mphamvu yogwiritsira ntchito pa 18GHz ndi yochepera 100W.
Kugwira ntchito kwa mphamvu komwe kwatchulidwa pamwambapa kumatanthauza mphamvu ya mafunde osalekeza. Ngati mphamvu yolowera ikuyenda, kugwira ntchito kwa mphamvu kudzakhala kwakukulu. Popeza zifukwa zomwe zili pamwambapa ndi zinthu zosatsimikizika ndipo zidzakhudzana, palibe njira yomwe ingawerengedwe mwachindunji. Chifukwa chake, index ya mphamvu yamagetsi nthawi zambiri siperekedwa kwa zolumikizira payekhapayekha. Pokhapokha mu zizindikiro zaukadaulo za zida zongogwiritsa ntchito ma microwave monga zochepetsera ndi katundu, mphamvu yamagetsi ndi index yamphamvu yachangu (yosakwana 5μs) zidzayesedwa.
Dziwani kuti ngati njira yotumizira sikugwirizana bwino ndipo mafunde oyima ndi akulu kwambiri, mphamvu yomwe imagwiridwa pa cholumikizira ikhoza kukhala yayikulu kuposa mphamvu yolowera. Kawirikawiri, pazifukwa zachitetezo, mphamvu yomwe imayikidwa pa cholumikizira siyenera kupitirira theka la mphamvu yake yokhazikika.
Mafunde osalekeza amakhala opitilira pa nthawi yozungulira, pomwe mafunde ozungulira samakhala opitilira pa nthawi yozungulira. Mwachitsanzo, kuwala kwa dzuwa komwe timakuwona kumakhala kopitilira (kuwala ndi mafunde amagetsi), koma ngati kuwala m'nyumba mwanu kwayamba kuzima, kumatha kuonedwa ngati ma pulse.
Kuti mudziwe zambiri zokhudza ma antenna, chonde pitani ku:
