Hi Incold Its good to hear of someone else in this area who also gets BBC1 etc. As far as I can see, I am about 55Km further south of you and a little to the west so you should have things a little easier. Mind you in fringe receptions area like this there can be peaks and troughs just a few...

This is an update about my 3.7m dish. Sometime in late summer last year, we had a lightning storm which must have damaged the LNB as it just stopped working. I replaced it with a new Invacom C120, and although the system worked during the day, BBC and ITV would break up early evening. Then...

Hi Incold You are about 60km NNE of me so should have similar reception conditions. With my set up, heavy rain does not seem to cause a problem, although I did loose most of my channels when the dish filled up with snow during the winter. Normally, I am never awake at 1am to see if the TV is...

Hi Can you answer a related question? I currently have two dishes and two receivers - a Pace SkyBox for Astra2D with a feed from one dish (3.7m as I live in Italy) and a GBsat using Diseq to select a double LNB for Hotbird and Astra 1 on the second, 1.2m dish. With the FoxSat HDR box, with...

That's the best news today. Problems with dish I can fix - problems with the satellite, no chance. PJG

Hi I have also lost Astra 2D reception. It was OK last night, but then we had a torrential storm with rain and hail during the night. Checking at lunch time, I found no Astra 2D channels but I can still get Radio 4 and Channel 5. There is no visible sign of damage or movement of the dish...

Corviello suggested I make some signal strength measurements during the day to get an idea of the variation. These are all taken with my Satlook NIT spectrum analyser inside the house at the end of about 50m of coax. Times are all local Europe summer time (BST +1). The first number is the...

Some more thoughts 1. The Channel Master 1.2m dish has a published mid point Ku band gain of 42dB, while that of the Prodeline 3.7m dish is 50.7dB. So I should have an increase of some 8.7dB. The measured improvement in gain with the same LNB etc. at 10964H is only 3.8dB so unless the...

I started again Friday morning. My first concern was the focus. The specified focal distance was 1372mm. First I measured the dish diameter - 3660mm, then the distace from the faceplate to the crossing point of the strings. This was actually 60cm, rather than the 61cm specified by Prodeline...

On Thursady, I finished the stand that allows me to work inside the dish. It is made of 30mm steel L section angle, with the base and supports bolted down to the concrete pad. Two wooden boards on top allowed me to keel or stand inside the dish to attach the feed mounting arms. (042.jpg and...

Now that I have my green laser pointer, I can mount the feed horn. I wrapped the laser in two places with a thin layer of sticky backed foam followed by layers of clear packing tape until it was a slide fit into the waveguide. For the Invacom ADF-120 adjustable feed horn, the protursion of...

I got the modified Prodeline feedhorn back from the engineer shop today - a good 10 euros worth. Now the Invacome adjustable feedhorn slides inside and is secured with two set screws. I have about 15mm of focus adjustment, which should be OK for fine focus. Next week I should get my laser...

Lake Garda is in the north of Italy, I live in the center 80Km south of Florence, so its not practical. If you could give me a price for both sizes plus courrier delivery from Cyprus, I could transfer money to your account either in the UK or Cyprus. Any little improvement helps so it will be...

Where can I buy them? PJG

Iceman - I see what you are getting at. I think I will have 1-2cm of focus motion. The Prodeline dish also has adjustable bolts holding the 4 struts to the dish. I plan to use them to get the focus set according to the book, then adjust the position of the Invacom horn for fine focus. From...
