• Short antennas for 160m - Often it is not possible to erect a full quarter wave verticals, especially on 160m or even more so at 600m. In this article N6LF illustrate some ideas.

• Antennas for 160m - The best results work when you have an antenna with a large vertical component. It is difficult to get a horizontal antenna (dipole) high enough to be an effective antenna on 160. However, there are several easy things you can do with your present antenna to initially get on the best amateur radio band

• 30m vertical dipole - The 30 Meter Vertical Dipole is constructed from #10 stranded insulated wire available in most hardware stores. The feedpoint uses a T-section of PVC pipe. The coax loops through the PVC pipe to provide strain relief. by W1TR

• 5 Band Telescopic Vertical Antenna - 5 Band 1/4 wave Telescopic Antenna. The 20m to 10m, antenna is simple and cheap to make, and has a performance that matches commercial antennas but at cost considerably lower. The design was purposely based on a telescoping fibre glass fishing rod as this allows it to be easily stowed away in the car.

• The Gamma Match - The gamma match was originally invented as a means of feeding vertical monopole antennas for medium wave broadcasts, which were earthed at the base for lightning protection- Hams are more likely to use a gamma match to feed a dipole or loop element, but the basic theory is easier to understand for the case of a quarter wave monopole.
