This project is a Bullseye LNB holder integrated with the 2.5 turn helical antenna for QO-100. You can just simply download the files or you can also read the article below to understand what and why I did. If you could not be bothered to read the article below, then do not complain it did not work for you. If you decided to read and then you want to complain – I do not care either 🙂

If your antenna is NOT on my list – it does not mean my design will not work for you.

You need to print our on the paper 1:1 PDF drawing and check against your LNB holder – see pictures below to see what is to do.

I would consider tweaking the holder to match YOUR LNB holder, however under one condition: you will send me a very detailed drawing – see samples at the very end of this website. Also I will need a link to the antenna seller’s website so I can have it for the reference.

Just recently I have added to the existing designs versions with the N socket – much neater, but you will have to get the socket exactly the same as I used. More info further down.

Warning!! Some pictures below show older versions of the 3D printed parts – don’t get confused! Also some 3D printed parts don’t look nice as they were printed using my old 3D printer. Now the quality is amazing.

If you wish to purchase an assembled QO100 BullsEye LNB Integrated 3D Printed Holder, send me an email to pawel@rozenek.com with your request and details.

For the purchased LNB holder, if you wish I can add for free you callsign printed at the back of the holder, like you see on the pictures below. The free downloaded files come with M0PPR logo.

Default colours:

holder – ORANGE (printed callsign black), cover – WHITE, clamp – BLACK

Multi colour 3D printing starts – first few seconds of the printing in the video below are slow, as for the best bed adhesion the printer is not trying to speed up, but then the printer I use is a beast 🙂 Please bear in mind, to get the holder (just the holder!!!) fully printed – it takes 9h!!!

The full set of the holder, clamp, cover is 16h of non-stop printing on my very quick printer!!! The standard printers are usually 2…3 times slower!

A small introduction.

I am an active user of QO-100 – the amateur geostationary satellite. I created my base station and also I have designed and made a portable version. For my base station initially I used a standard DC8PAT 3D printed antenna which is kind of great design but I decided to improve it especially for a portable work. Later on I have also replaced my base station with my own design of the LNB holder.

DC8PAT has some design issues which I eliminated:

• you need to have a lathe (I do have) for making 3…4mm thick reflector, otherwise making it with a metal file is a disaster.
• The antenna has no drain system, if the water (likely) will get inside – it will stay there for kind of forever! I had to drill a drain hole to eliminate the problem in the original DC8PAT design.
• Original cover fits 3.5 turn helical antenna, however for my need of having 2.5 turn helical antenna the cover is way too big.
• The original DC8PAT design (non commercial version) has a very difficult system of bonding/screwing a helix support to the aluminium base.
• DC8PAT antenna will work correctly only for dishes 60cm or bigger – it will clash with the arm for small dishes – see some pictures below.
• easy to snap the base holder if overtighten

Advantages of M0PPR QO-100 Bullseye integrated antenna:

• You do not need lathe to make it – you can use 100mm 0.2mm thick copper plate. Cut it with scissors!!!
• Weatherproof design with drain holes.
• It comes with a skew indicator (hahaha).
• It just looks very nice! 🙂
• The cover thread is compatible with the DC8PAT design.
• If for whatever reasons you decide to use 3.5 turn helical antenna, my cover is not long enough – but you can use the DC8PAT design – the thread size is exactly the same.

Do my M0PPR QO-100 Bullseye integrated antenna comes with any design problems?

Unfortunately, yes.

• antenna has no proper N connector attached to the base – I struggled to add one when use with a thin copper plate. So you need to add the coax cable and soldered it directly to the copper reflector – before (!) the reflector is fixed to the 3D printed holder. It is not a true anymore. I managed to add a N socket version too! However, you will have to get the socket exactly the same as I used. More info further down
• The coax hole diameter is 8mm as it is designed to my favourite SSB7 aircel coax. If you need to use any thicker cable – you have to use an adaptor. Probably drilling a bigger hole (eg. diam. 10mm) will also work. Or try to modify my file.
• It was designed to work with LNB Bullseye – massive chance other brands will not fit the 3D printed holder and clamp.
• if the size of the LNB arm in your antenna is different to what I design – you cannot use it unless you manage to modify my design to match your needs or you create any kind if an adaptor (or even you use hot glue to bond a bigger holder to a smaller LNB arm).
• If the angle between the LNB arm and axis of the LNB is different, then you will lose some gain!! All assembly drawings provide the angles and dimensions – check them!
• I would consider tweaking the holder to match YOUR LNB holder, however under one condition: you will send me a very detailed drawing – see samples at the very end of this website. Also I will need a link to the antenna seller’s website so I can have it for the reference.

Pictures below show the problem with the DC8PAT and small dish:

How to make the antenna – see step by step list below. Also check the pictures under the list.

1. Print the main holder (choose which design you need by analysing assembly drawings in the table above). You can print 1:1 assembly drawing to check if your original LNB holder matches the design – see pictures below.
2. Print the cover – STL HERE
3. Print the clamp – STL HERE
4. Make the copper reflector (2 versions available) – some pictures below
5. Print the helix winding jig – STL HERE, some pictures below. Please note, the design asks for the 42.3mm inner diameter of the helix antenna, which means the centre of the 3mm copper diameter is 45.3mm. However, after winding up the copper always springs back a bit and the diameter becomes 1mm greater, so the winding jig wire centre to centre diameter is 44mm (not 45mm).
6. Wind 2.5 turn helix antenna using a solid 3mm diameter copper bar over the jig

Socket dimensions:

When fit the socket, add a very small amount of silicone:

The socket with the previous version of the reflector, so that’s why you see some unwanted holes. The drawing for the N socket version of my integrated antenna is showing now correct holes for that version.

Will my design work for you – here how to check it

The pictures below show how to check if one of my designs will match your LNB holder. Just print all (currently three) A4 drawings in 1:1 scale and check! 🙂

Picture above shows a perfect matching holder

Picture above shows a holder with not matching angle

I would consider tweaking the holder to match YOUR LLNB holder, however under one condition:

you will send me a very detailed drawing – see samples below and link to the antenna seller’s website so I can have it for the reference.

A story about Sky 45cm x 65cm disk – a very popular dish in the UK!!!

Few months ago I started making a portable station for my car – the aim was to be able to keep it in the car boot under the horizontal curtain, so nobody see what is inside.

I was doing some experiments with 40cm dishes like the one below:

Unfortunately the signals, especially for receiving was very weak, my signal on QO-100 was relatively good as I was using 40W Chinese PA with a real 20W RF power @ 2.4 GHz.

60cm dish I experimented with was OK from signal strength point of view, but it was too big to go under the curtain in my boot.

Finally, I found solution. If the antenna cannot be higher, but can be wider, why not to use a old rusty Sky dish – 45cm x 65cm? The solution is now absolutely perfect!

During the design process, however, I found some challenges. The standard dish LNB arm was clashing with the reflector, so the solution was to cut it!

The cutting instruction:

The hole was drilled using the 3D printed holder as a guide!
