    Can I use aluminum wire (instead of copper) to build a biquad antenna for TV reception?

    Certainly you can, most of the factory antennas are made of aluminum, in amateur constructions copper is used because it is easy to connect by soldering

    Well, you can only that aluminum cannot be soldered ...

    There are special alloys and fluxes for soldering Al

    There are, but their cost will exceed the cost of the antenna, or at least a copper wire ....
    BTW, a 4.8mm copper tube is about PLN 8 / meter

    Outwardly, I do not recommend the connector oxidizes very quickly. In general, aluminum is quite a nasty material in contact with other metals.

    If I would make copper and solder, do I have to put it in a can? Is it just for decoration?
    It is such a temporary solution with this aluminum.
    What do you think about such


Topic summary

The discussion centers on the feasibility of using aluminum wire as a substitute for copper in building a DVB-T biquad antenna for TV reception. Participants note that while aluminum is commonly used in factory antennas, it poses challenges for soldering due to oxidation and the need for special alloys and fluxes. The cost of these solutions may exceed that of copper wire, which is easier to work with. Concerns about the durability of aluminum connections and the potential need for protective measures, such as using a can, are also raised.
