A beam type of antenna at a height of 70 feet or more will provide greatly superior performance over the same antenna at 35 feet, all other factors being equal. A height of 120 feet or even higher will provide even more advantages for long-distance communications. To a distant receiving station, a transmitting antenna at 120 feet will provide ...

Interpret words literally. If it says the tower may be a certain height, it legally means the tower excluding attachments. If it says the combined structure, aggregate assemblage, or other side k ilar words, then it means the whole thing including attachments. 3.
Nov 13, 2024 · The radiation pattern on 20m is the familiar donut shape with maximum RF energy at 25 degrees to the horizon at a broadside azimuth of 85 degrees. There is even about a half S-unit of gain. For good DX the radiated signal is still at unity gain down to 10 degrees. Low EFHW on 30m Elev=65 deg Azimuth=50 deg.
Jun 1, 2018 · "The following proposals are excluded from land-use authority and public consultation requirements: New Antenna Systems: where the height is less than 15 metres above ground level." In other words, you will have to go through the Industry Canada process for an antenna over 15 metres.
Apr 7, 2018 · Apr 8, 2018. #10. Captain KW has the best answer. The best MINIMUM antenna height is one wavelength above rf ground. In the case of cb freqs, this works out to 36 feet to the base of the antenna. I have always had good success both local and dx using the 36' height.
Height of antenna and support structures. Local administrations in the United States may control the height of radio antennae so long as they do not restrict the height beyond that expressly authorized by the FCC As previously stated, the FCC authorizes the minimum height necessary for the radio service to function properly. If the federal ...

get a jpole and get it up high if that's what works, but truly, understand, no one can do anything about you putting an antenna on your home unless you are in an HOA, and then, it's still up for debate :) you put an antenna on the peak of your house, and add even as little as 5-10w and you should be good.
