    No commercial 10MHz-50MHz antenna ? How to build?

    I don't find any commercial antenna operating at 10MHz-50MHz. Why there is no horn antenna work at 10MHz, the size of the horn antenna is not so big.

    Then I have to build a simple antenna connected with an RF signal generator with an SMA connector.

    I guess the antenna I built is based on inductor loop wire, but the SMA connector has two nodes (a signal and a ground), how I can connect the SMA with the inductor loop wire with only one node ? Should I just leave the ground node of the SMA connector floating? Thanks.

    Calculate the size of a 10MHz waveguide

    Did you press the "Calculate" button on that online Horn Antenna Calculator?

    NO, I didn't press the "calculate" button. I think that is the reason that it has a small size. Thanks.

    I thought not

    Re: No commercial 10MHz-50MHz antenna ? How to build?

    You should give some additional informations. Are you planning a wide band transmitter or receiver antenna? A wide band receiver antenna might be made electrically small (with respective losses), a transmitter antenna effectively not. Tuning a small antenna to a different frequencies in the 10 - 50 MHz range is however feasible.

    Yes! We ALL like using waveguide at 10 MHz. That way if it is raining, we can park our cars inside of it so they do not get wet
