Vhf Uhf Wagon Roof Placement

Since the uhf band covers a much larger range of frequencies than vhf 1 4 wave antennas can range anywhere from 3 to 6 inches in length so using the proper length antenna is important.

Vhf uhf wagon roof placement. I have a repeater friend who s considering selling me his ft 857 and if that doesn t happen i ll be getting an ft 7900. After changing and consolidating radio systems a few spare hardlines from a lab open and no plans to reuse. I have one that s 19 high that goes in and out of parking garages with no trouble at all. If you do select an all mode all band transceiver or separate transceivers.

The vertical angle of radiation of a signal. Got two choices put up a dual band vertical vhf uhf or hf dipole. Company okayed letting us ham brothers put up an antenna. The advanced technology of the dedicated uhf vhf multi directional elements deliver range and reception in less than ideal locations.

It supported several of my mobile station goals nicely. My vhf uhf antenna is mounted on the hood with a trunk lip mount. The clearstream 4max uhf vhf indoor outdoor 70 mile range hdtv antenna is designed for those living in suburban and rural areas. As with a lot of fairly new hams i d rather not drill a hole in my truck s roof.

I have a pickup 01 f150 and i want to mount a uhf vhf antenna. Decide whether you want hf in addition to vhf and or uhf. With quick connect parts the assembly only takes a few minutes. Frequencies vhf and uhf communicating between any two points on the earth rely primarily on high frequency hf signals propagating through the ionosphere.

Of these the center of an automobile roof is considered the best for mobile antenna placement followed by the center of the trunk lid low silhouette antenna. The only one that is not would be an 8 ft 1 4 wave 108 stainless steel whip mounted on a spring in the middle of the roof. This also includes front. Vhf uhf and cellular have a much shorter radio wavelength and therefore the antennas are relatively compact and mounting is less of a problem than for cb.

The shadow is available in uhf 800 900 pcs and 2 4 ghz frequencies for either nmo or direct feed. Typically lower channels 2 through 13 are broadcast on the vhf frequency while higher channels 14 through 83 are broadcast on the uhf frequency. My choice was a compact all band all mode transceiver from yaesu the ft 857d. 2 basements and 4 floors agl.

Two separate transceivers one for vhf uhf fm and one for hf ssb. This is not a very practical setup not to mention ugly. Building has 2 x 15 feet radio towers on roof separated by about 200 feet. That s my everyday antenna and i can work all the local repeaters from anywhere in the county with it.

The earth s ionosphere acts much like a mirror at heights of about 150 miles.
