However, if the only repeater you intend to use from your home is a 2m machine, and you have no interest in other VHF/UHF band operations, then a single band VHF antenna may be your. The antenna has a full 300kHz bandwidth on 80m between 3:1 SWR points. I even purchased all the materials for a dual band cubical quad, only to realize during assembly that my roof space is not enough for a bulky and heavy antenna. N6BT has done repeated tests that show that a flat-top dipole mounted at the same height as the apex of an. Phoenix VHF/UHF JPOLE Base Antenna 2M/70CM 143-149 MHz + 437-450 MHz. Components. Listen…and learn! Sponsored by DX Engineering, “ARRL The Doctor is In” is an informative discussion of all things technical. The capture area of a 6 wire cage dipole has increased 5 times ! An EIGHT wire antenna increases gain of capture by 7 ! Although it is hard to work with, and build this antenna, for amateur radio use, it's one of the best. Also available is the popular FM & DAB antenna for a more discrete combined reception solution. By Marian Anderson,* WBIFSB diameter of 7/8 inch (22. Band Hopper III Multiband Portable HF Dipole Antenna System *** IMPORTANT NOTE: if you are using a Band Hopper with our 10m Compact Travel Mast, attach the antenna with a cable tie to the top of section 11 (counted from the bottom).

HF Tri-Banders High Gain, Compact and Light Weight Trap Beam for 7-21-28MHz CD 218 series is a compact sized trap beam antennas designed for the operation for 7, 21 and 28MHz offering performance characteristics comparable to a full size antenna. It was designed and patented by Dr. Keeping these constraints in mind, I used a computer antenna-modeling program, S Figure 1—Dimensions for VE7CA's 2-element wire triband Yagi. Not too bad for an antenna that cost roughly $35 to make and took about an hour to actually build and tune. Ham Antennas. Material list for building a 4 Elements Yagi 1″ X 0.
