Antenna height considerations
Longwave/Low frequency antennas
At VLF, LF and MF the radio mast or tower is often used directly as an antenna. Its height determines the vertical radiation pattern. Masts and towers with heights around a quarter wave or shorter, radiate considerable power towards the sky. This allows only a small area of fade-free reception at night, because the distance at which groundwave and skywave are of comparable strength and can interfere with each other is severely restricted (approximately 40 kilometres to 200 kilometres from the transmission site, depending on frequency and ground conductivity).
For high power transmitters, masts with heights of about half the radiated wavelength are preferred because they concentrate the radiated power toward the horizon. This enlarges the distance at which selective fading occurs. However, masts with heights of around half a wavelength are much more expensive than shorter ones and often too expensive for lower power mediumwave stations.
For longwave transmitters, however, the construction of halfwave masts is infeasible in most cases, either for economic reasons or because of problems with flight safety. The only radio mast for longwave with a height of half a wavelength built to date was the Warsaw Radio Mast (which did not survive). For frequencies lower than the longwave range, masts have to be electrically enlarged by base loading coils or structures on the top, because the heights required for masts of even a quarter wavelength are too large to realize physically.
Use is not normally made of masts higher than five-eighths (5/8) of a wavelength, because such masts (except for some special constructions for high power mediumwave broadcasting) exhibit poor vertical radiation patterns. The heights of masts for mediumwave transmitters normally do not exceed the 300 metre (1000 foot) level.
Sometimes cage aerials or longwire aerials are used for LF and MF transmission. In this case the height of the tower may be greater than is usually the case. Because towers or masts used for cage or long wire aerials are grounded at the base, they are especially suitable for supporting antennas for UHF or VHF broadcasting.
Shortwave/High frequency antennas
For transmissions in the shortwave range, mast height has no influence on efficiency when the masts are used for supporting the antenna. Normally, shortwave transmitters do not use masts higher than 100 metres.
Antennas for UHF/VHF
For transmissions in the VHF and UHF range, tower importance and value can vary depending on the area to be served. The cost of a tower must be re-couped primarily through advertising carried on the broadcasts, especially where there are no license fees charged the listener. Considerations such as population density, line-of-sight signal range (affected by terrain), and the costs of tower construction and maintenance versus height, must all be weighed in choosing an ideal tower size. Often there are restrictions related to flight safety governing maximum allowable tower height. Two shorter towers may be a better option then a single taller tower. Also, a higher tower might not be useful if the signal is blocked by terrain or if all the listeners are in a concentrated area and a higher tower cannot pay for itself.
Antennas for point-to-point radio services
In most applications line-of-sight is required between the transmitting and receiving antennas for point-to-point services, and antennas may have to be mounted at a certain height about ground. For microwave radio systems, it is not always possible to use long transmission lines between transmitter and antenna, so towers with equipment rooms or cabinets close to the height of the antenna may be required.

What is this annoying static?
When I’m listening to AM radio stations or shortwave stations, this annoying, loud, buzzing static overtakes the whole spectrum of the band. I move the dial, but it appears in every frequency, unless the signal is really strong or I’m on FM. Then, just as it comes, it goes away. (it begins moderately loud, grows louder steadily overtime, then it fizzles out)
It appears only after sunset, at night. I measured the lengths of both the static and the space between statics. They are regular.
The static lasts around 30 seconds. The space between statics lasts two minutes and 30 seconds. What do you think is the source so I can remove it, or at least get away from it? 10 points for best answer.
Without knowing the neighborhood etc it would be hard to answer as it can be something in the house that is used (such as a controller for the heater) or like what happens where I live, salt gets deposited on the electrical transformers causing the short and noise
But the best place to start is to check this website out as they are known as some of the best independant RFI (radio noise) people out there
