I have a noob question about receive antennas. Is it a common practise to use them for regular operation? Almost on every other QSO, the operator is complaining about noise on the band so I am curious as to why HF receive antennas are not as widely offered by antenna manufacturers or mentioned in operation books. For example, in the ARRL handbook, I don't recall seeing anything like install a RX antenna for lower noise and use another antenna for TX. While this approach seems more logical to me, since I live in an apartment surrounded by all sorts of noise. And, is a small loop a good RX antenna to start with for apartment usage?
