Pe canicula asta colegul nostru 233YO320 - "Blondul", a luat masurile de rigoare si-a montat doua "coolere" micute care s-au potrivit exact pe radiatorul statiei Avanti Grande dupa cum se si vede in imagine.

How to use an CB auto antenna indoors

First what you need is a good CB antenna, in my test I'm using one made by Sirio the "Blue Line 1000" with a big magnetic mount made from steel, fixed on a "ground" available in my room .. an unused cast iron radiator near the window.

If you want to improve a bit your artificial ground, and do a better vertical polarization, then use a metallic grid.

Make a  coil from the coax cable on the middle ... 7 to 10 turns on 10 cm (4") diameter (this is a Choke loading coill resonant on freq.)










For tuning I use an Zetagi MM27, that's made for small power (under 100w).

Yep, it's working well, and this is the SWR on the middle of CEPT band. Nice I think :-)












Anyway, the best antenna for indoors use is of course an home made :-)
This one, has a 5 ft long, and is tune with an base magnetic loading coil + tansmatch ; there is no need for a grounding system.

Marius din Hunedoara este de astazi colegul nostru de club cu indicativul 233 YO 214 , iar datele lui de contact pentru expeditia de QSL-uri sunt deja trecute in CallBook.
Are in dotare mai multe statii, de baza este un Avanti Grande dar nu stiu ce antena foloseste, oricum lucreaza QRP.
Mult succes in activitatea de radioamator CB si legaturi DX cit mai frumoase stimate coleg.

Avanti Alpha la DX in AM

 

Iata un scurt video facut astazi ora 19:15cfr cu o legatura in AM pe CH36  facuta cu o statie mobila "Spanico" coordinate di Palermo in Sicilia :-). Initial l-am auzit pe "Spanico" pe CH40 de unde am facut QSY pe 36.

Distanta este de cca. 1170 km.
