The original design of the balun device, protected by patent, contains a bandpass filter, which is well agree on the antenna cable in the operating frequency range, reduces noise at its output and provides reliable lightning protection TV. This design of antenna is designed for reception of television decimeter waves (UHF) frequency range 470-862 MHz, allows us to keep the analog (21-69к)and digital (DVB-T/T2) signals. The antenna is passive and does not have a built-in amplifier in this regard does not require electric power 220 volts. If you need to increase the level of the received signal external power amplifier can be installed separately.

,,,one port is horizontally polarized and the other is vertically polarized...!!!

That's how it should be...

Is that what you want...??

,,,do you want something like this...???

,,,f/D=0.25...you can see the difference...!!!

If we had to participate in field tests of a transceiving apparatus, part of which was various types of antennas, and as Omni-directional, they are independent from the design and the claimed gain in performance for range transmission and reception is insignificantly different from each other. A significant difference was their price. Of greater importance, as we understand it from practice, had such option antenna as it is efficiency, which directly connected with the working surface (the larger antenna size than she is better), but not with the stated gain. So simple homemade omnidirectional antenna is not what is not inferior to similar fancy designs. For beginners, we don't would advise to grasp for the production of Omni-directional antennas with a large gain such as collinear or the like. Without skills and lack measuring instruments to achieve from these structures excellent results not will. The antenna that we propose to assemble, has an important property. First of all, it is quite simple and broadband (bandwidth 200 MHz), this means that miss relative to the fundamental frequency of transmission and reception as a result of the inaccuracy construction will be difficult, which is an important factor in the case the lack of measuring devices. However, simple a homemade antenna will differ markedly from the purchase of the product may because a nested design energy of creativity yields results. The antenna is a quarter-wave vibrator with a counterweight

Pupe, try a Strella-11 omni antenna too....!!! I think we still need to work on this...

Also available for sale are the more powerful Stella-8 and Stella-11 antennas with a gain of 8 dBi and 11 dBi, respectively.
