Portable Two Ways Radios - UHF Versus VHF Technology!

Executive Summary of UHF Radio by Dave H Clark

Uhf Radios

Portable two ways radios are no longer confined to police and military departments. Since UHF and VHF are two technologies that have been employed in these wireless systems; it would prove helpful to know the difference between the two.

A huge number of people believe that portable, handheld two way radios with UHF technology have certain inherent benefits over VHF. Furthermore, you cannot keep aside the cost factor as it is always of prime consideration. The foremost advantage of UHF is that it supersedes the probability of interference due to its more available frequency spectrum.

There is no denying that interference due to inauthentic outputs from other radio frequency equipment is comparatively less in UHF frequencies. Even the digital devices or electrical equipment which are in UHF frequencies tend to experience lower obstruction. When you have decided to buy two ways radio, keep in mind that UHF radio will cost you more in comparison to the similar VHF radio. However, the higher cost of UHF equipment is not unreasonable as expensive ultra-high frequency components are used in it. Other manufacturing costs in UHF Radio are also higher specifically the amount of time consumed in adjusting the equipment and its performance verification. When it comes to battery life; VHF scores better as its battery life is always longer compared to its contemporary UHF Radios. If you want to have larger wireless installation, the cost of antenna splitters, antennas and preamplifiers is often quite low for VHF equipments; but they give better performance.

So, from the point of view of cost, VHF finds favour with the masses; while UHF Radios has lesser chances of interference. Still the choice can be affected by a number of applications issues:

No matter whether you go in for VHF or UHF Radios, diversity systems are most often suggested. Further, it holds more importance for UHF Radios as it is UHF frequency that gets troubled by dropouts because of multipath.

It would also be noteworthy here that in some specific situations, VHF devices work better compared to UHF Radios. Handheld portable two-ways radio with VHF and UHF technology fulfils different needs of different individuals.

How to Choose Between UHF and VHF Portable Two-ways Radio?

Though the initial costs are higher in two-ways radio compared to cellular or Enhanced Specialized Mobile Radio (ESMR) systems, you get some real benefits in the form of lower flat rate airtime which is usually available in wide area portable two-ways radio. VHF and UHF both technologies fulfill the purpose of communication. If you need to use this wireless handheld radio in more than one city, then in that situation, VHF radios which operate on the special frequencies will prove to be best as well as an economical choice. To avoid these frequency conflicts, it is better to use frequency-agile UHF radios.

You must know that there are a number of situations where VHF based portable two-ways radio will be the right choice in comparison to UHF Radios and also at substantially lower prices. You must compare both UHF technology based portable two-ways radio and VHF technology based radio and then consider your own requirements to have optimum benefit out of these radios.
