Ant\u00e9na na CB, ktor\u00fa som spom\u00ednal v \u010dl\u00e1nku<\/a> pred p\u00e1r t\u00fd\u017ed\u0148ami na lok\u00e1lne spojenia chodila, no nebolo mo\u017en\u00e9 ju umiestni\u0165 \u00faplne vertik\u00e1lne. Tak ma napadlo, \u017ee v\u00fd\u0161ka krovu pod ktor\u00fdm bola umiestnen\u00e1 je asi 3 metre, a v pohode by sa tam vo\u0161la ant\u00e9na Ground Plane.
\nV haraburd\u00ed som na\u0161iel plastov\u00fa krabi\u010dku na p\u00e4tu, PL konektor, 3 zdierky, jeden trojmetrov\u00fd dr\u00f3t, a star\u00fa 4 metre dlh\u00fa bielu trojlinku ktor\u00e1 sa pou\u017e\u00edvala kedysi na nap\u00e1janie spotrebi\u010dov.
\nDo krabi\u010dky som osadil konektor a zdierky do ktor\u00fdch sa pri\u0161robuj\u00fa dr\u00f4ty. \u017diari\u010d som zavesil do \u0161picu krovu, a trojlinku som rozdelil, a pou\u017eil na 3 protiv\u00e1hy. Tie som ani neskracoval, iba som ich rozvinul po podlahe. Vypad\u00e1 to zauj\u00edmavo, pok\u00fa\u0161al som sa to aj odfoti\u0165, ale je tam m\u00e1lo svetla.<\/p>\n

No podstatn\u00e9 je, ako to chod\u00ed. Podarilo sami to vyladi\u0165 tak, \u017ee na 15m m\u00e1 PSV 1:1, na CB a 10m asi okolo 1:1,5. Na CB som za\u010dal dost\u00e1va\u0165 o nejak\u00e9 to esko lep\u0161ie reporty, a ke\u010f vietor f\u00faka t\u00fdm smerom, tak otv\u00e1ram na z\u00e1kladn\u00e9 4W aj opakova\u010d na Remate.
\nNa 21MHz som urobil zo 100W HZ1MD (Saudsk\u00e1 Ar\u00e1bia), a dnes v CQ-M conteste asi 40 prev\u00e1\u017ene rusk\u00fdch stan\u00edc.
\nV\u010dera ke\u010f bola pekne otvoren\u00e1 28MHz, urobil som tam s nov\u00fdm QRP\u00edtkom<\/a> na 5W YL3DR a PD0MNV.
\nUvid\u00edme \u010do bude \u010falej, vrchn\u00e9 KV p\u00e1sma s\u00fa ka\u017ed\u00fdm d\u0148om chodivej\u0161ie…<\/p>\n
