Where to buy 13m receive only antenna with low price and high quality. We are your best choice, all the information about 13m receive only antenna are available as below.
13m receive only antenna Description
Our 13m receive only antenna , which uses a shaped parabolic reflector, provides high gain and exceptional pattern characteristics as well as low VSWR. The main reflector surface is comprised of adjustable aluminum panels. The 13m antenna structure consists of the pedestal, reflector, sub reflector and the feed system.
13m receive only antenna Features

Wind for stowed: 35m/s (Drive the antenna to the position of pointing to the sky and stowing)
Preservation wind speed: ≤55m/s (lock at the position of pointing to the sky and stowing, the antenna won’t produce failure and destruction.)
(7) Three-proofing measures
It has the ability of moisture-proof, mould-proof and rust-proof. In its life there won’t be obvious corrosion. The steel parts adopt the treatment of hot zinc spraying or hot zinc dipping or sand blasting, and then coating corrosion resistant primer, finally spraying white finishing paint. The aluminum parts adopt anodic oxidation treatment, zinc yellow primer coating and surface with white colored paint.

Antesky is a professional TVRO antenna manufacturer, which was established in 1985 under the support of Chinese governmental research institutions. At previous time, we mainly customized antennas for Chinese aerospace and military application. From the year 2008, we began to produce civilian antennas. However, Antesky manufactures civilian antennas according to military standard all the time, so the antenna quality is with high reputation in the world. Antesky can provide antennas from 3m diameter to 50m diameter, including VSAT antenna, Large Satellite Dish, TVRO Antenna, Flyaway Antenna, Marine TV Antenna etc.
