Andrew Roos, ZS6AAA for a multiband antenna, since it can be easily matched by most wide range antenna tun-ers and will not cause an unacceptably high loss in the coax. For example, if the antenna is fed by 100 feet of RG-213 at 7 MHz, then I instead made two antennas: one center-fed and one end-fed. I did perform S11 on both to trim for the 30m band. Unsurprisingly, both are the same length. The VSWR for the center-fed is under 1.5. The VSWR through the step-up transformer for the end-fed is also under 1.5. Dipole testing electronicsA multi-band end fed wire antenna presents a potential problem in that a ¼ wave length antenna cut for say the 80 metre band will present a feed impedance of about 70 ohms however when the same antenna is used on the 40 metre band the feed point impendence will be several thousand ohms and therefore difficult to achieve a match even with a ...I have been running an end fed in my attic for three years.
