Turning waste into wealth: Satellite Radio in the reuse of waste equipment – sat
Hebei Industrial Dissection With Satellite Radio The development of the new emerging devices, some devices were originally used have "retired." Fortunately, in many TVRO's no need to hand some of the equipment are such that they leave the useless gesture. In fact, there is no lack of these devices, fine, or to be of value, directly or through a little transformation can be achieved after the re-use purposes. Especially for the working-class friends, the good use of these "retired" equipment, we can achieve not only save money and Fever The purpose, which is double benefit.
1, the use of unipolar Tuner: General unipolar single-output narrow-band tuner and dual-polarized broadband high-frequency head is higher than the gain, the old head is a high-frequency Ka ton example. In the receiving process, when using small diameter antenna reception is poor, may wish to change this unipolar high-frequency head, and sometimes get unexpected results. Multi-satellite reception in a pot, such as satellites to be received by a polarization of programs are entirely possible in this unipolar high-frequency dual-polarized first instead of head.
2, the feed tray of use: Now, some with high-frequency head together Sell The feed tray has been to use plastic material, whether from the intensity or the effect of view not from the actual use and before the metal feed plate. Such as the purchase of the feed tray with a plastic high-frequency head, would be able to feed the original metal plate, to improve the reception. You can also set the two old feed processing, assembling together, it became a common saying, "binary feed", the processing Make See related press method Magazine The introduction.
3,13 / 18V switch use: The switch is connected to the dual polarization feed using a device, now uses dual polarization LNB, which naturally no one switch use. Multi-satellite reception in the pot when the satellite to receive the polarization parameters of each group show the same way or would like to receive a satellite of a polarization of the program, the 13/18V switch can be combined with DiSEqC , by setting the number of machines of different polarization voltage to achieve switching between different satellites.
4, unipolar waveguide tube and the waste feed LNB's use of dual-polarized: in a pot of multi-satellite reception, the two satellites to be received by close proximity, the installation of two high frequency head position also to be close together, but the lower part of a short inconvenience Ku head fixed, then you can feed the interception of a unipolar or retirement of the waveguide tube waveguide dual-polarized C head tube connected to the Ku head lower, like fixed. For example, the author is fed with a 1.5 meter antenna 134 ° EC-band and 138 ° EKu band binary program, for two Xinggui bit shy of 4 °, to be on C-band feed tray for processing. However, I have chosen DirecTVKu head lower for a short, fixed hard disk in the C-band feed. First C-band feed was then removed part of the side plate from a scrapped ASKBC-218 high-frequency head interception of a waveguide tube, get a bike Inner Tube Wrapped around the lower part of the DirecTVKu first, then the interception of the waveguide tube head of security in the Ku, the outer edge of "two brothers good" glue. Processed through this, Ku-band feed for the first fixed to the C drive on very easy.
