. Both can be used on multiple bands though the random. END FED 640 Meter Multiband HF Antenna Introduction This EARC project produces an inexpensive, multiband, end fed HF antenna matchbox that is quick and easy to setup and use. Knowing that, the impedance ratios needed to match an End Fed wire to our 50-ohm feeds should be 361 to 641. . com. .

Table 1.

The exact length is not critical If you don&39;t have room for the 160 or 80 meter version.

I have a full list and tutorial video if you would l.

This is due to the wire end impedance of a 12 dipole being close to 2450, which is the feed point impedance of an EFHW (ie at the secondary of the impedance matching transformer).

Other. . Mar 13, 2020 The EFHW-8010-2K End-Fed Halfwave 2kW Multiband Antenna with mounting kit by Myantennas.

A monopole antenna is like a center-fed dipole, with one-half of the antenna being the reflected image of the radiating wire inside the ground.

Step 2.

Things did not go quite according to plan.

9-inch diameter, featuring just 0.

. The key to end fed antenna success is the matching network interface between the long wire antenna and the coax feed line and feed line choke at the transceiver.
