[QUOTE="Old Satellite, post: 5471, member: 175277"] [updated:LAST EDITED ON 18-Jun-02 AT 08:00 AM (GMT)]It is pretty diffcult to resolve you problem, without high costs, or a more simple and greater effective larger dish. as you are aware this is truly the most effective solution. It is unlikely that you can modify or improve the perfomance of your current Triax dish to the required level of signal that will allow for the effects of rain attentuation etc. You will improve marginally for example if you were to chose a Gegorian type dish (expensive) there is a 90 cm availible. A 0.5db PLL (phase locked loop)lnb will also help in the quality of the recieved signal (expensive) they are better than the standard Dswitched lnb this can only be utilsied to full effect with a poloriser either mech or magnetic. They will help possibly contrubuting Triax to Gegorian 90cm = 0.3-0.5 db LNB gain advantage = 0.1-0.3 db Lower generally across the whole frequency range The additional skew benifits of the mechanical poloriser would potentially be lost as a result of the insertion of the device - 0.1 db At best you may achieve an extra 0.5 db at a substantial cost + 250.00 Are you 100 % sure that you can not utilise a 1.2 mtr dish - can you install in your garden for example? Which transponders on 5.2 east specifically are you looking to receive at your location ? What is the current coax cable that you have used? and how long is the cable ? PS the Echostar 3000 has a reasonable digital level sensitivity and is not easily improved upon without once again high costs. Old Satellite [/QUOTE]
