<\/a>P\u0159ed \u010dasem jsem nav\u0161t\u00edvil Tom\u00e1\u0161e OK1TP abych obdivoval jeho kr\u00e1sn\u011b „zarostlou“ zahradu a st\u0159echu.

Kdy\u017e m\u011b p\u0159ed n\u011bkolika dny informoval, \u017ee je d\u00edlo dokon\u00e1no hned jsme se domluvili na n\u00e1v\u0161t\u011bv\u011b. Sto\u017e\u00e1r o v\u00fd\u0161ce 21m jsem si um\u011bl vcelku dob\u0159e p\u0159edstavit, ale kdy\u017e jsem uvid\u011bl ten 4 el. QUAD m\u00e1lem jsem spadl z kola.
\nI kdy\u017e nepat\u0159\u00edm ke skaln\u00edm p\u0159\u00edznivc\u016fm kr\u00e1tk\u00fdch vln, p\u0159esto odbivuji \u00fasp\u011bchy a pr\u00e1ci v\u011bnovanou na v\u00fdstavbu podobn\u00fdch syst\u00e9m\u016f. J\u00e1 s\u00e1m se chyst\u00e1m na stavbu sto\u017e\u00e1ru ji\u017e n\u011bkolik let, ale bohu\u017eel jsem se k tomu j\u011b\u0161t\u011b nedostal a tak um\u00edm ocenit, \u017ee i tak velice pracovn\u011b vyt\u00ed\u017een\u00fd \u010dlov\u011bk jak\u00fdm Jarom\u00edr je si na to \u010das na\u0161el.
<\/a>A te\u010f ji\u017e n\u011bco o vlastn\u00ed konstrukci. Ant\u00e9na pracuje od p\u00e1sma 14 a\u017e do 28 MHz s optimalizac\u00ed rozte\u010d\u00ed jednotliv\u00fdch prvk\u016f pr\u00e1v\u011b pro 14 MHz. P\u0159i d\u00e9lce boomu p\u0159ibli\u017en\u011b 7,5 m a stran\u011b quadu cca 5m se jev\u00ed jako v\u00fdrazn\u00e9 \u0161et\u0159en\u00ed prostorem. Vykazuje i pro takto n\u00edzk\u00e9 kmito\u010dty vlastnosti podobn\u00e9 ant\u00e9n\u00e1m na VKV jako nap\u0159\u00edklad re\u00e1ln\u00fd p\u0159edozadn\u00ed pom\u011b\u0159 v\u00edce jak 20 dB \u010di v\u00fdrazn\u00fd vliv p\u0159i sm\u011brov\u00e1n\u00ed ant\u00e9n. I zisk, kter\u00fd se pohybuje p\u0159es 14 dB je v oblasti kr\u00e1tk\u00fdch vln opravdu k neuv\u011b\u0159en\u00ed. Mysl\u00edm, \u017ee pro men\u0161\u00ed zahr\u00e1dku je to opravdu nejkvalitn\u011bj\u0161\u00ed \u0159e\u0161en\u00ed, kter\u00e9 jsem kdy vid\u011bl, proto\u017ee i funk\u010dnost zahrady z\u016fstane bez probl\u00e9m\u016f zachov\u00e1na.
Co se technick\u00e9ho vybaven\u00ed hashacku t\u00fd\u010de dominje zde tak\u00e9 p\u0159\u00edj\u00edma\u010d v\u00fdroby RFT <\/a>s ozna\u010den\u00edm EKD 300 a jako hlavn\u00ed TCVR pou\u017e\u00edv\u00e1 Jarom\u00edr KENWOOD TS-850 jeho\u017e sign\u00e1lu na p\u00e1smu dod\u00e1v\u00e1 s\u00edlu koncov\u00fd stupe\u0148 dom\u00e1c\u00ed v\u00fdroby s v\u00fdkonem 750W.
