Co do HV-6 i HV-10 to polecam ten link http://www.qsl.net/pa0fbk/hampage_uk.htm gdzie jest parę słów o małym usprawnieniu "Especially for this very shortened antenna it is very important to use a counterpoise: A wire connected to the ground connection of the transceiver and layed out on the ground. A 1/4 wave antenna without counterpoise works very bad, in the hotelroom, throw it out of the window (not the antenna, but the counterpoise and do not loose the end, hi). The optimal counterpoise length (depending on surroundings) is about 0.8x1/4 wave, so for instance for 40m it is 0.8x1/4x40 = 8m.".
Mi z HV-10 w warunkach hotelowych przy 5W z 817-tki udawało się zrobić całą Europę na KF na JT65 (no ale to JT65 - niesamowita skuteczność). |
