Dipole Stack Array UHF TV Broadcast Antennas: TV6-5282
Constructed entirely from stainless steel, these broadband UHF TV 4-stack dipole arrays are designed for wide band vertically polarised TV transmissions where a high gain is required.
Key features are :
- The 120 MHz minimum bandwidth is ideal for multiple UHF TV station transmissions and antenna sharing,
- 7.5 dBd gain,
- Neat design with an internal power divider included,
- Factory tuned and spaced ready to mount,
- Stainless steel construction ensures a long service life, and
- Minimal wind loading.
The standard range consists of 3 fixed frequency models each factory tuned to cover a designated bandwidth within the UHF TV frequency range 520 to 820 MHz. Alternatively, clients can specify any 120 MHz bandwidth they require.
- Model TV6-5282-A : 520 to 640 MHz.
- Model TV6-5282-B : 590 to 720 MHz.
- Model TV6-5282-C : 680 to 820 MHz.
- Model TV6-5282 : Specify any 120 MHz bandwidth.
Return loss will be optimised to better than -20 dB across the chosen UHF TV transmit frequency range. An N-Female connector rated for 200 watts input power is located inside the base of the mount tube.
For higher 500 watts input power, add the suffix "-MP" to the order code.
To achieve even higher transmit power and gain, these dipole arrays can be mounted in tandem using another power divider.
TV6-RS Rear Reflector Screen
The TV6-RS stainless steel rear reflector screen can be fitted to any of our TV6-5282 series dipole stack arrays.
Fitting this screen to the dipole array will achieve :
- A cardiod shaped restricted radiation pattern at the rear.
- An increase in nominal forward gain to 10.5 dBd.
- Front-to-Back ratio is improved to better than -24 dB to meet the Australian Communications and Media Authority standard.
Clamps are supplied to mount the screen to the TV6-5282 dipole stack array. The antenna tune will not be affected when this rear screen is fitted.
