This is a pity, because most hams would put up a wire antenna especially for the lower bands where beam antennas are more difficult to erect. Fritzel FD 4 Multiband Antenna Reviews Home Reviews For: Fritzel FD 4 Multiband Antenna Category: Antennas: HF: Verticals; Wire; Loop eMail Subscription Registered. By 1937 the Windom was described “as multi-band antenna that can be employed on harmonically related 160, 80, 40, 20 and 10m bands with acceptable levels of VSWR”. Note the circled area at 1/3 length - this is where the impedance is about the same for all these bands. The Fritzel FD4 antenna is a classical antenna in our series of HS4 Legendary Multiband Wire Antennas. Este diseño también presenta unos bigotes de gato para trabajar las bandas WARC y los 15m. This Windom antenna was marketed in the late 70's and early 80's as Smithe's Windom. The circuit diagram shows how the module should be interfaced with a. Australia/New Zealand. Though works on the other bands with an ATU. . It is still available from They continue the Fritzel antenna business. He will operate on 40, 30, 20m, including activity in CQ WW WPX CW Contest. This result suggests that sequences outside the C and GMR35H08 elements restrict fd4/fd5 expression to the ventral imaginal discs. Fritzel. The 4-band Fritzel model FD4 is a special version of a Windom antenna. 800 Watt FD4 multi-band antenna with 1:4 super balun Project for a multi-band antenna for the 80, 40, 20, 17, 12, 10 and 6 meter bands, including a 1:4 impedance transformer and a current balun handling 800 Watt with common mode attenuation up to 40 dB! Complete balun and 1:4 impedance transformer See full list on iw5edi.
