For a coaxial fed, "One Antenna Do All" you can't beat the off center fed antenna. Each end fed antenna needs a feed line choke at the radio end of the coax to stop the antenna common mode current (on the coax braid) from getting into the radio when transmitting and also to stop RFI common mode noise when receiving. Unlike many END FED antennas on the market, this one does not require the Antenna Tuner to operate. END-FED ANTENNAThe ULTIMAX DXTREME end-fed antenna covers from 1. Be the first to review “Shakespeare® 8ft End-Fed VHF Antenna – White/Nylon” Cancel reply. The end fed seems to have a slight edge, but I would put this down to it being higher in the air rather than any inherent design advantage. RadioWavz Dipole antennas are the simplest practical antennas from a theoretical point of view; current amplitude on such an antenna decreases uniformly from the maximum at the center to zero at the ends. End Fed Antenna Reviews. This describes the pictured EFHW (End Fed Half Wave) antenna in the photos below. However, when using it with an End-Fed. The impedance of the antenna is in the 300 to 600 ohm range so I feed it with a 1 to 9 impedance matching unun. But be warned – end-fed antennas can be noisier and also cause more EMC/interference problems. A Distributed Antenna System, as the name implies, “distributes” signal. You can also L shape it or zig zag it or slope it if you are limited on room. This antenna is a full wave antenna on forty meters but has to be fed at a different location if one wants to use 50-ohm coaxial cable. But for everyone else, YMMV. The first antenna I purchased from Ron convinced me that the proper engineering and application of end fed antennas can be remarkably successful. When fed from the center, a dipole makes for an easy impedance match to 50 ohm coax. No need of Auto Tuner. Normal multi-purpose tuners often will not match the high impedance presented by an end fed half wave. Our showroom facility is a focal point for the local amateur radio community.
