    How to extend your Antenna

    Construction Parable.


    I state that what I'm going to write has no absolute value but is the result of personal experience and the material used is fiberglass kit will be enough to have a 5 Kg where comes the glass cloth resin (5 kg) and the Catalyst Brushes with this material you can build a dish from scratch from 150 cm.per material will each own choices as needed.




    I do not make any difference between the description of the construction of satellite dish to the Parables and expansion of the existing procedure is intuitive in a way or another.
    On this occasion not take into consideration the construction of Parables from scratch by Dima and cast, but apart from the construction of the first jig and cast and then the next steps are the same, we here consider the fact those who have a dish to play and / or expand.
    1) Remove the disk from the installation by removing the 6 screws (Gibertini) and bring the disk in a place sheltered from wind and convenient to carry out the work, place the dish to the ground with a pen and draw the 4 key points from the point at the dish arm as firm foundation on which we draw a dash at the exact center and maybe a "B" (low) dividend perfectly vertical and horizontal reflector make the dash top with an "A" then dash to the right with a "D" and the hyphen on the left with an "S" the sign of the hyphen must also be given on board the parable, the parable at this point we split into 4 parts.


    2) When it comes to making an extended plan parabolic scoring four points highlighted in the extent of increase measured by a hyphen inside edge reflector.

    3) This section covers both the new construction of the dish is ready to cast the realization all'inetrno (or external) other dish which will become a clone.
    A) Obtain the rolls of foil from the kitchen Cuki type (or other) also get the glue to Parati, prepare the glue very diluted by mixing with water.
    B) Now begins the hard work and delicate which depend on receiving the best or worst dish we are going to create ...... if you can resort to an aide, with a brush of glue enough impregnamo Disc (or Football ) begin to lay the foil to the bright side up, being the center of the roll coincide with the 14.5 cm mark on the top center dish, roll out plan seeks to address right to the other center in the meantime which is very low hard we try to minimize the wrinkles on aluminum so if there's aide can do this using well-inch and minimizing defects which will remain at the paper is not Aluminium elastic, finished this first draft of the Central 'Ideally, cut the roll into 2 parts to bring it from 29 cm to 14.5 cm to cover the rest of the disc on either side without gaps (better sovraporre) with fewer folds, otherwise do our best with the entire roll.


    4) Take the cloth and place it over the glass dish covered with aluminum and then do all the work of tailoring with a scissors cut along the edges of the dish (a little more) and cut and sovraporre all folds formed by the different geometrical figure.



    5) Prepare the resin using a container (eg) 500 ml fill up to 2 cm from the edge of resin and then pour the catalyst is sufficient as an example of measuring a bottle cap full of water stic containers to pour and mix quickly.
    6) You start to soak the cloth stretched over the glass dish covered with aluminum, you start to soak the brush soaked with resin from the center of the disc and spiral work (soaking the cloth with the brush with tap straight) outwards so if they had remained bent or air to carry it out with scissors always at hand for some action, it is preferable Flick the tip of the brush and when a part is not to insist otherwise impregnated fails, you need to fill a number of times your can of catalyzed resin to complete a new (clone) 125 cm dish. Keep in mind that even if the plan is not perfect impregnated the signal is reflected from the foil that it should be made well.







    7) After work through the brush somewhere to remove as much resin can then put it in a clean jar pour a small amount of detergent with clean water and passing it repeatedly in some unnecessary surface, put the detergent on a rough sponge and clean hands .
    8) When the new dish will be thoroughly dried proceed to report on it marks the 4 basic partitions present on the Parable of "mother" turn the Parables ataccate 2 and proceed to drill the mounting holes to make new ones through the "mother" at this point to satisfy your curiosity remount the double reflector on the plant and observe the results, it is important to check all the receivable satellites so that we know with high probability that its yield will be when used alone without the Parable " mother "that supports it.
    9) Remove the double disc and pull it back in the lab with due caution in every way making sure not to damage the aluminum foil until it will (later) interned by the GRP, releasing at various points in the Parable daughter from parable "mother" (or cast), it will come off with ease thanks to the aluminum foil that holds currency, the film of course will remain well-welded aluminum to fiberglass.
    10) Do you want to expand now if the disc in Parabolic Reflector "mother" will be refreshed every sign of departure and reference made you decide that the measure will reach the dish in the photos of the procedure consists of extending the measure of a Parabola of 125 cm to 150 cm to proceed as placing the photo reflector daughter on the Parable "mother" additions will be made in stages 2 to 4 parts for vertical and 2 horizontal part then we will shift down a the top one right one left, work will begin putting in the dish to broaden the film Aluminium enough for the 13 cm of added (cuts abound) it will stand on the cloth of glass cut to 13 cm or more (end surpluses cut respecting the exact addition in the entire circumference) and all'impregnamento proceed with the resin to dry and hard once you proceed to the other 3 parts, remember to adhere well to the two floors and if Parabolic necessary based weights without excessive force.

    10) Now we made the dish 150 cm it can get very good but for the moment is not self-supporting (thin then flex) then proceed accordingly, rests the Parable "mother" turned over and raised a few bricks or another a few inches above the ground floor and placed in apoggia on the new dish, being careful to observe the direction of the signs and respect the difference of measure by which the "daughter" Exceeding the "mother" in all points scored, based on the cloth cut glass to make it appropriate to join at any point and proceed as before with the catalyzed resin with the brush to impregnate the glass cloth, follow all the stages of drying and hardening is just take it from there turn the Parable "mother" up and tucked into the Parable daughter doing exactly the same signs of both dividing and in particular to align the six holes between the two Parables, put some small weight and defer the rest to at least ' tomorrow.
    11) We are the next step all layers of fiberglass processed data as said before will always on the back of the reflector 3 to 4 layers.


    ricompletate after the existing holes on the first layer and the dish is ready to be mounted by itself instead of the Parable "mother" in this context will need to drill a small cut where he will be stuck in the arm after removing LNB support reassembled later.
    12) If you want to proceed with only the extension reflector existing procedure remains the same except that for safety and comfort after plotting (as if) the 13 cm extension at the 4 key points with aluminum foil and the fiberglass we keep at least 3 cm inside so that work done then put under the expanded part reflecting the soil turned to rest on the dish that we have to expand we match perfectly the fundamental signs of the two parties with a draw marker to accept all the outer circumference cut with Moletta little extra that we built and it should fit perfectly on the original dish used to secure metal flaps flexible enough screws 5 mm edge reflector and piercing as the GRP Photos .
    When the work is completed whether a new dish or invert an extension to the ground based on the Parable of "mother" completely centered just so stuck right should make a small jig to a piece of wood 13 cm by 15 cm or more by part of the frame should be made to the other marker at 13 cm distance you drive a nail into the wood with the nail board leaning against the Parable "mother" will round the dish and the pen will trace the exact edge of the new 13-cm exact distance larger than the dish "mother" maintaining the characteristics of ovals, then Moletta tagierà exactly is the line drawn, if you want a small brush you can soak the cut edge.


    With your imagination measure for I have forgotten.

    Very interesting but I think that dish wouldnt last long. When stronger wind come this will break.

      And to get a perfect parabolic shape will be really difficult. The arm the LNB might need adjusting as well.
      Technomate TM600 + 1m motorised dish (TM2300 motor).
