Žádám o radu, jak jsou zapojeny AL pásky z obou dipólů. V návodu na montáž o tom není zmínka.

The classic high-gain antenna
The Evolveo GT's built-in amplifier, external power supply and overall parameters make it an excellent choice of antenna for use in areas with a weak TV signal. It has an integrated LTE filter, which filters the signals from mobile operators so that there are no complications with the TV signal reception. Its wide frequency range of 470-862MHz allows the reception of all TV channels.
Receiving TV in HD
The antenna can receive 4K/UHD high definition TV signals. Its special aerodynamic shape makes it more reliable because it is more resistant to snow and wind than antennas with a classic shape.

Efficiency, noise and spatial gain graphs
A UHF VSWR (Voltage Standing Wave Ratio) graph demonstrates the efficiency of the antenna for the UHF band. A VSWR coefficient equal to 1 indicates the conversion of electromagnetic waves into an electrical signal. The VSWR graph for the GT antenna achieves a very balanced efficiency and virtually no frequency band exhibits lower efficiency than 70%. With exceptions, the value of the VSWR is not higher than 3.
The graph shows the value of NF UHF antenna noise, and the GT exhibits low noise values even at large signal gains. The UHF Polar chart shows the areas with the largest signal gain.

Easy adjustments to the antenna position
Mounting the antenna is very easy. A rotary joint makes it possible to find the ideal positioning without the need to loosen or tighten screws.
