Technical Notes

Note on beams used on 30 and 40 meter bands:
These bands are considered a "bonus" with our multi-band beam antennas. The performance of our beams is usually equivalent to or better than a dipole at the beam height. Over distances of 4000 miles and greater, their performance on these two bands is similar to (or better than) a quarter-wave ground plane with 18 radials. The receive noise level is significantly better with our antenna than a with vertical.

The feed point impedance of a 40-meter antenna varies widely with height above ground. Due to this variation in impedance, some difficulty may be experienced in tuning the antenna for 30 and 40 meters. The presence of metal structures and other antennas in close proximity to the beam may also affect tuning of the beam.

It is very important to use a high quality MIL Spec 50 or 52 ohm coax cable with the Sommer antenna. RG213U or RG217U are recommended, due to their high mechanical stability.
The balun furnished with the Sommer antennas is a low-loss air core type using RG142 (BU) Teflon cable. The balun will handle 2.9 kW continuous output at 30 MHz with a loss of only 0.05 dB.
In the interest of technical improvement, all specifications are subject to change without notice or obligation.
