are all antennas the same?

All digital antennas receive the same picture and sound quality; we just give them a familiar name. ... The real difference is the uncompressed signal received with an antenna. There are channels, and then there are sub-channels.

The answer is yes, but it won't be over these high-frequency antennas. It will be basically where 4G is today, so you won't get the high-capacity [service].”

If you don't have one that's capable of high-definition playback — that is, HD — then it's seriously time to think about upgrading. But, to repeat: What you don't need is an "HD antenna." There is no such thing as an HD antenna. ... An antenna is just an antenna, and a signal is just a signal.

In the attic directional antennas always work better than omnidirectional antennas. In certain areas it's possible that some incoming TV signals may be too weak to be received with an attic mounted TV antenna but can be received with the same antenna mounted outside.

Old contract analogue tv aerials had plastic caps covering the wiring. Digital aerials have f type connectors which screen the wiring. ... Aerial grouping is nothing new but most analogue aerials are of the wrong group to pick up the correct tv channels. The top part of the UHF band was used to transmit freeview.

Yes it's exactly the same. Voltage, pins and everything. Anything bought for the UK works as is in Singapore for electrical supply.

Assuming no obstructions, a single CB antenna has a uniform, circular signal pattern. It can send and receive in all directions equally, as illustrated by the picture below. Dual antenna installations don't have the same signal pattern.

Looking for a super-easy to install CB antenna? If so, you can't go wrong with the best magnetic CB antenna. Beside painless mounting, this type of antenna has fantastic performance and can give your radio a really good transmission range. However, the magnetic CB antennas you'll find on the market are NOT the same.

Meteor has been owned by Eir for 12 years and over time their plans, handsets and offers have become virtually identical in all but name. They even use the same phone masts, so you won't notice any difference in service or coverage.

Items you will need That requires two different types of antennas, or a dual antenna that can receive both types of signals. If you have two different types of antennas, you can hook them together to make your channel hopping easier. Connecting two antennas can also help improve the reception of signals.

Are all Cobra walkie talkies compatible if on the same channel? Not only are different Cobra models compatible, but you can talk to different brands (eg, Motorola) tuned to the same channel and code.

Dipole Antennas Include: One area in which dipole antennas are often used is for the reception of VHF FM broadcasts. Many Hi-Fi tuners and other radios have input sockets that will accept the input from a coaxial feeder, and where no external antenna is used, a dipole antenna can provide an excellent solution.

Frequency is inversely proportional to the physical size of the active element of an antenna system. The antenna for GSM900 is twice as big as the ones used for GSM1800. Both antennas as usually made of dipoles that are stacked together in a single assembly mainly to increase gain.

If buying new all the Harmony hubs are all the same across the packages, just be careful with older/used hubs as there WAS a difference and may not work.

Given the same transmitter output power, in the absence of ANY interference, the lowest-frequency channel will nearly always be the best. This is because higher-frequency radio waves do not penetrate matter (including air) as well as lower-frequency waves.

However, for Sky Q, there is absolutely NO need to give them different SSIDs, as Sky Q will only connect on 2.4 GHz to a BT Hub, and will completely ignore the 5 GHz band, which it uses for Q box-to-box communication only.

The general rule is: the higher the frequency, the smaller the antenna. Students in RF usually start with the dipole antenna, which is half a wavelength in size. Making it longer will degrade its performance.
