pentru inceput avem asa :
-Zona austriei de nord detine o depolarizare a undelor radio .
-In uncraina avem de a face cu doua tipuri de propagare , propagarea normala pentru aceasta perioada cat si propagare mai puterinica , peste perioada aceasta in zona NE a ucrainei .
-In romania aveam propagare normala , indicele de stabilitate al propagarii este exact pe culoarul montan de la drobeta pana la suceava - botosani , propagarea specifica ploii si anotimpului de primavara se regasete exact in sud la zona turnu magurele . Mai avem o propagare de schimbare de are , de la cel cald la cel rece pe zona montana a apusenilor , sau propagarea la fruntea muntiilor , dar aceasta nu va dura mai mult de jumatate de zi deoarece frigul va pune stapanire pe aceasta zona si fenomenul va scadea si muta .
-Bulgaria va avea o propagare supeba si stabila 2 ore si jumatate intre culoareul ruse - silsitra , o propagare dunareana mai bine zis , o propagare ce va avea exact sensul est - vest si vest - est .
propagarea de munte , este cea cuprinsa de la vrata , lovech , sofia , pazargik , plovdiv , arsenovgrad , smolien , karjali , hascovo . Aceasta propagare are stabilitate exact pe zona plovdiv - pazargik . Culoarul de mare stabilitate a propagarii normale de 4.5-6% din acest moment o detine , kavarna - edirne , un culoar tipic pentru stabilitate si propagare de pana la 80-100km fara conditii avansate .
- Turcia , are doua fronturi de propagare de instabilitate cuprinse intre antalya , manavgat , seydisehir , cumra , konya , karapinar . In zona alaya , in orele urmatoare propagarea se va ameliora si va urca in instenistate .
Cipru , propagarea cipriota detine loc superior in acest moment deoarece in jumatatea sudica a ciprului , Paphos si limmasol , larnaca , au propagarea de peste 18% , anormala pentru aceasta perioada , dar cu variatii catre zona famagusta catre orele urmatoare . Propagarea are stabilitate pe regiunea sudica a nicosiei si chiar in zona peristerona .
Libia - propagarea in stabilitate pe cheiul cuprins intre TRIPOLI , Misratah , Surt , bengazi ,sahdhat.
Spre orele urmatoare aceasta propagare va deveni instabila deoarece pe medirerana va apare un front de deploazirare ce va inteti scaderea aceseia.
SIRIA - lataqkya jableh va avea o propagare de stabilitate . adusa de mare , si aceasta nu va depasi zona Bergai jabhet . La pasrtea opusa de vest a siriei , aveam propagarea de la ABU KMAL spre ESHARA si eshara jisr shaddadah . Aceasta propagare este una stabila si normala pentru aceasta perioada , avand doar variatie spre scadere in orele urmatoare . Traiectoria acestei propaagari este spre Irak . Ar mai fi de zis ca propagarea din nordul siriei , granita cu turcia , are traiectorie exact pe langa suruc , akcakale , cu culoare spre ayn al arab-->alforat , sensul propagarii este de la est catre vest , propagarea va deveni turca in orele urmatoare .
Marea neagra - CUloarul zonguldak sevastopol se va redeschide in aceasta zi , este iar un prilej bun de dx si nunumai . Stabilitatea este medie , aceasta propagare avand tendinte spre simferopol fedosiia kerch ... Propagarea are posibilitatatea sa urce spredjankoy .

Today new athmoferic air mass appear in mediteranean sea :
In zone Tunis to south italy .. new propagation appear . Duration is maxim 4 hours but the athmospherical front closed by the new pressure .
libian propagation in NW appear at mid power level , in 2 zones : TRIPOLI - Ghadames . At the mirsatah zone to SURT appear at sea propagation high . this fenomen not receive in cityes but the distance sea to city is small <12km .
Sea mediteranean - to arabic zones long distance tropo , summer echivalent at peak mid level is in this moment . this fenomen appear in the most popular culoar - CRETE - AL JAWF .
The last summer the indicator of the tropo say - maxim peak level tropo to 1000Km W to E direction in zone al najaf , al anbar , kmal zone , latakya - larnaca ..

Folositi careva pe FM antene tip " J " ? Ce parere aveti de ele ?
19-03-10, 19:58
zvartoshu

am fosloit antena circulara Jhcp .. ma dadea pe spate cum sa zic ! un semnal de pe diretcia nord , il luam si pe sud si pe sud est si pe est si pe vest si sud vest.

kuki222

Multumesc de raspuns dar eu ma refeream la o antena J-pole ( pe scurt antena J ) si nu la antena Jampro pe care ai folosit-o .
O antena J-pole este o antena verticala , omnidirectionala , usor de construit si cica si buna ( vezi Google ). Asta ma intereseaza .

Salutare,

Scuzati interventia mea,va rog dar DX-ul ma pasionat dintodeauna.
Dintre multele antene pe care le-am construit una sa evidentiat in mod deosebit,datorita cistigului si directivitatii.
Este vorba despre antena SWAN dimensionata intre frecventele de 88MHz si 634MHz,cuprinzind 10 dimensiuni in FIF+FM+145 MHz radioamatori ,si 13 dimensiuni in UIF intre canalele 22 si 41 OIRT/CCIR.
Ar fi pacat sa se piarda aceast tip de antena,are intradevar ceva de oferit celor care au nevoie de servicile ei.
Depaseste in cistig si directivitate multe antene FM+Tv existente astazi pe piata chiar si faimoasele antene cu elementi in X,bag mina in foc pentru antena asta cum se spune,iar daca elementii sint facuti in totalitate din teava de cupru nu are egal.
Am testato in cele mai dificile situatii,inpreuna cu alte tipuri de antene si intotdeauna a iesit pe primul loc.

Corect mouse ! swan e swan .. nu se compara !
Cat despre J-pol .. am pe casa , cu ea am dat lectie anc care spunea ca nu se poate face receptie de distanta langa 3 posturi de radio ce au maxim 6/5kw putere totala radiata pe 6 antene verticale gamma !:gathering:
Exemple langa gurillaa .. >?
FM+ 94.4 si 94.0 voces campi .. zona unde pe aparatele de radio apare brum .
La mine apare VOCES si FM+ , chiar si vara am sporadic pe 94.500Mhz si 95.100!
