100W FM from Avanti Grande
strap for 40w
60wFM/40ssb
Like I show you in a past post this is the "secret" modification made in Avanti Grande & the family CB radios made to obtain 100 Watts (40w or 60w depending how do you put the strap on transistor...) output in FM, but this one has a price to pay ... you lose the AM modulation and variable power. If you really want to do this, then at least use a good wire, because you must bypass (or strap) a strong DC current (8A).

Asa Nu, asa Da !
Antena verticala de CB 11m din imagine este montata undeva in Deva si este un exemplu de amplasament gresit ales... De ce ? :-)
Iata o alta verticala tot undeva prin Deva ... asa DA !
Daca sus de totului nu se poate nici cum (cazul meu) atunci mai bine va departati de cladire la cel putin un landa (5...10m, 20m e optim pt un bloc de 4et.) si 1m deasupra solului pt o verticala (L/2 pt dipol orizontal/inclinat) dupa care puteti testa locul ales folosind o statie portabila.
La montajul pe fatada cladirii macar inclinati antena la cca.45..50grd si evitati pe cit posibil apropierea ei de obiectele metalice mari (streasina), oricum cimpul e mai slab dar virful e mai degajat un pic si unghiul de plecare pt dx mai mic.
