Can I mount two antennas next to each other? If using two antennas on a vehicle, it is recommended to have a minimum of 300mm separation distance between the antennas to ensure no interference.
The distance between the two diversity antennas should be at least one quarter of a wavelength, and the distance between them will affect the signal. Antennas that operate on different frequencies should be placed so that they will not interfere with each other.
Antenna Positioning: Distance Between Antenna
For effective diversity performance, AB antennas should not be positioned less than ¼ wavelength apart, and ideally, they would be placed ½ to one full wavelength apart.
Horizontal Separation
If both antennas on a mast are connected to remote radios, then a minimum of 2-3 feet of vertical separation is typically OK. If one antenna is connected to an access point radio, then it will be transmitting much more, and thus interfere constantly with the other.
If antennas are placed too close together, the booster may experience oscillation. Oscillation occurs when the antennas pick up each others signals and create a feedback loop.
Any time a TV signal is split, it will encounter insertion loss that will weaken the signals distributed beyond the splitter. If you experience signal issues while using a splitter, you may need to install a distribution amplifier or a preamplifier.

NMEA recommends 6 feet of vertical and horizontal separation between the VHF and AIS antennas. Most manufacturers recommend more.
You put the two antennas at different heights. Thus, when one antenna is receiving out-of-phase signals, the other is receiving in-phase signals. If you combine these two antennas properly, you wind up with an average signal that doesn't vary much. This is a form of diversity reception.
The rule of thumb to set the antenna physical dimension ensures that the current travel path P approaches to a quarter of wavelength at the lowest operational frequency.
A: For the best performance, we typically recommend placement of your TV antenna at the highest point available to you and with a clear line of sight to the broadcast towers to minimize the possibility of obstructions between your antenna and the broadcast towers it is receiving signals from.
It is commonly known that electromagnetic waves are obstructed by physical media. Thus, isolation can be increased between two antenna simply by placing objects in the path between them.
With antennas on both sides of your vehicle, you're much less likely to have large dead spots because the antenna system can "see" more. This is one of the primary reasons most 18 wheelers have dual antenna setups.
Can you put two antennas on the same mast? It's done all the time. There isn't a hard and fast rule because in most cases it doesn't matter.
The minimum clearance distance (for antennas on lower bands, same polarization) is one-half of the stacking distance for two of the same antennas. Example: The manufacturer recommends that you stack two identical 144MHz yagis 10 feet apart.
Antenna isolation is the technique of separating antennas that coexist so that there is only acceptable levels of interference between systems. S-parameters S21 and S12 describe the effect on port 2 due to port 1 and vice versa and determine the insertion loss and isolation between the antennas.
This antenna combiner merges the signals from a UHF antenna with a VHF antenna to a single downlead. The combiner is designed to mount directly to a mast using the adjustable mounting hardware and the housing protects the connections from corrosion.
The curvature of the Earth will block most over-the-air broadcast signals at roughly 70 miles. According to the current laws of physics, it is generally impossible to deliver the 100 and 150-mile range claims some antenna manufacturers boast.
Yes you can. Use a 2 way coax splitter “backwards” to combine the signal from the 2 antennas.
Of-cause you can buy multiple antennas for each TV but most of the time channel availability will vary from one TV to another due to location in your home. So how to connect one HDTV Antenna to multiple TVs. The answer is simple to use Coaxial Cable Splitter and RG6 Cable.
The range of a 2 Watt UHF CB Radio is up to 10km in ideal conditions.
Multiple TVs on One Aerial
It is possible, and relatively easy, to run multiple TVs from one TV aerial. All you need is the correct equipment. If your aerial is in total working order, there is no reason why you cannot run many TVs through it.
To assist, you may need a signal amplifier. Use a signal amplifier. If you have trouble receiving TV signals, place a signal amplifier (also called a signal booster) between the antenna and TV to boost the signal. This also helps with low-sensitivity TV tuners and DTV converter boxes.
Luckily, there is little chance of that, because Wi-Fi networks work on different frequencies than digital antennas. Digital TV antennas go up to a frequency of 693.25 MHz, according to Into Tomorrow. Wi-Fi routers, on the other hand, operate on 2.4 GHz or 5 GHz. That's a huge gap between frequencies.
