The Nalgonda district police busted a gang of three youths specialised in tower antenna works, engaged in allegedly stealing valuable components of various antennae and cell towers. About ₹40 lakh worth material — remote radio units, baseband units, batteries and cables — was seized from them.Get more news about Best Antenna Parts Exporters,you can vist our website!

Dhiravath Naveen, Dhanavath Krishna, both 24, and Dhiravath Mohan, 32, hailing from Miryalaguda mandal in Nalgonda district, police said, had been working as cell tower riggers and technicians.

Making good use of their skill, the youths allegdly stole components from cell towers of Airtel, Jio, BSNL and 11 baseband units and six radio units. In all, their activities were detected in Miryalaguda, Triupuraram, Vemulapalli, Madgulapalli, Nidamanuru, Neredugomma, Tirumalagiri Sagar, Peddavoora, Kondamallepalli, Devarakaonda and Chintapalli mandals.

Police said their arrests were made following a technical investigation into complaints of theft from Krishna Manasa colony, Srinivas Nagar and Ilapuram in Miryalaguda rural police limits.
System” is a word that gets thrown around a lot. What does it mean from the perspective of an amateur radio operator? Generally, I think of a system as a collection of parts, each with a distinct function, connected together electrically or mechanically to achieve some purpose that none of the parts can accomplish by themselves.

What about “antenna system,” then? What does that include? I consider an antenna system to be the parts and pieces between your radio’s antenna connector and the air in which the electromagnetic waves travel to and from other stations. Not all of those parts and pieces carry current. Your coaxial cable’s plastic jacket is an important part of the antenna system as you’ll find out if it ever gets a hole!  The same goes for that tree holding up one end of your dipole.

Parts of an Antenna System
Such a broad definition can make things look pretty complicated, but you can usually simplify a system by sorting the pieces into different categories. From a general point of view, your antenna system is made up of three types of parts: passive mechanical, active mechanical, and electrical. All of those parts contribute to how your station receives and transmits radio waves.
Let’s consider a simple antenna, say, a half-wave wire dipole for 20 meters fed by coaxial cable. What does that antenna system look like? If you start by designing and modeling this antenna in free-space, you’ll wind up with about 33 feet of wire (clearly an electrical part) having a classic figure-8 radiation pattern.

Since most of us don’t live in free-space (CQ NA1SS!) the antenna will be some fixed height above ground. The height makes a big difference in the elevation pattern, as the figure shows for several elevations. The electrical properties of the ground also determine how much of the signal reflects and how much is dissipated as heat. That makes the ground an important active mechanical part of the antenna system.
