Antennas : 160M
  • Wire antennas for the low bands - Experiments by G8JNJ on wire antennas for low bands. Based on these tests, conclude that for multiband (160 to 6m) operation, in a restricted area it is very difficult to beat a G5RV, especially the ZS6BK version.

Operating Modes : Stealth Amateur Radio
  • HF Antennas for restricted space - Arrl document about invisible antennas and indoor systems. It is important to consider that few compromise antennas are capable of delivering the performance one can expect from the full-size variety. But the patient and skillful operator can often do as well as some fellows who are equipped with high power and full-size antennas. The "cliff-dweller" may not be able to "bore a hole" in the band as often, and as easily, but DX can be worked successfully when band conditions are suitable.
