A short 40m dipol
To construct each side of the antenna proceed as follows. Cut a 10.25 metre length of 24/0.076 insulated wire, and a 160 mm length of 40 mm o.d plastic tubing

Antenas encurtadas tipo rigido com bobinas de compensacao
An antenna is intended to work in the 40-meter directional Yagi type cut to the frequency of 7,010 to 7,100 MHz, with a length of 4 meters. per element and with the deployment of a coil at 2 meters. from the center

Battle creek special 40/80mhz
This antenna is designed for 40, 80 and 160 meters to complement a tri-band beam normally taken on DXpeditions for 10, 15 and 20 meters, so six bands can be worked with only two antennas

Compact only 9m dipole for 40m band
Total length only 9m40 about less than a 20m dipole, It is a center loaded antenna
