The MFJ-1910 Telescoping Fiberglass Mast is 33 feet tall, yet collapses to a mere 3.8 feet and weighs only 3.3 pounds! You simply pull out each section and twist to lock. It extends to a whopping 33 feet -- a full quarter wave on 40 meters! 10m (33 ft.) is OK for this antenna. It works for both 40 and 80m. The length is not critical, as long as it is at least 1/8 wavelength long on the lowest band. If you put down 10 radials this length, you will have a good working vertical on both bands. If time and circumstances permit, of course it is better to use a few more.

The antenna is calculated for a specific length, usually 1/4 wavelength. The radials should always be the same length, but I have found that you can vary them about,. So on a 40 meter vertical you can have a few radials that are 34 feet (ideal 1/4 wave at 7.1 mHz), and a few at 38, and a few at 30 feet. It's an 1/8 wave vertical on 160 meters also. This antenna is 58 ft tall and is mounted on a hinged base. I chose 58' for Mid 80 Meter Operation. If you want 75 Meter operation make it 57 ft long. I like to use a home made current choke to keep RF from coming back on the feedline. Use 22 ft of RG-213 Coax Cable on 4" PVC. Figure 4 shows a typical model of a vertical with a radial system. Except as noted, the following discussion will focus on operation on 3.53.8 -or 7.07.3 MHz- as the operating band and 3.65 or 7.2 MHz as a spot frequency near midband. The conductors (both the vertical and the radials) are - lossless #12 wire.
