The simple broadband TV antenna works at the 615- 765-
MHz. Antenna has input impedance 300-
Ohm at the pass band. Antenna may be used with antenna amplifier
that has such input impedance. Antenna may be used with coaxial
cable with broadband
The antenna is a variant of the famous Chireix- Mesny Antenna.
Figure
1 shows design of the antenna. Figure 2 shows impedance of the antenna (antenna
placed at 7- meter above the real ground). Figure 3 shows SWR of the antenna
(antenna placed at 7- meter above the real ground). Figure 4 shows DD of the antenna
(antenna placed at 7- meter above the real ground).

Note I.G.: Chireix- Mesny Antenna was designed
in France by Henri Chireix, Chief Engineer
of the Societe Francaise
Radiotelectrique, and Rene Mesny,
Professor of Hydrography in the French Navy. Papers on the antenna
were published (in different variations) in the 1926- 1928s. Patent
H. Chireix: French Patent # 216,757, filed Mar. 10, 1926.
Antenna originally
was used for directive radiation and reception at short waves.
Lately the antenna was widely used at VHF- UHF waves.
