Only a tiddler but as cheap as I have seen one of these at £20 just south of Preston:

Not second hand, but the seller claims this is 'low cost'.

Radio Telescope package with 3m antenna; Receiver, controller & software Tx/Rx | eBay

Antenna Type: Ring focus antenna. (This antenna can be used also for Tx/Rx application in L, X, C, Ku and Ka-Bands). Receiver unit with high-resolution digitizer and high dynamic range detector. Digital Display of Antenna Position and Error Signals.

www.ebay.co.uk

The reflector (and king post) look suspiciously like the one I have at the back of the lockup, which I believed was good for Ku band only.
Perhaps the cassegrain front end improves rigidity.

That's a "bargain dish" at around $31,000 delivered to the UK???

It is their base model upgradeable L-band radio telescope

Looks like a Suncom/Probecom 3.0m dish to me.

The price from a quote I recently obtained for the fixed dish dual Rx C-Band version was $2350 USD plus $410 USD freight to Felixstowe from China.
Dual Rx Ku-Band version slightly more expensive.

Dual axis motorisation options also available.

I saw this Uniden dish with VBox on Facebook. Size not given 1.0 - 1.2m??

 

[Channel Hopper]

That is a 90cm Precision with the standard offering polarmount for a 2" post.

 

[Joolz]

Oh yes, I should have recognised the feed assembly.

 

[nelson_b]

Yes .... 90 c.m. Identical to one i bought a few years back ... nice little dish .

hi guys i know probaly a very long shot but would anyone have a polarmount for a channel master 1.8m offset dish?any help truly appreciated cheers.

or would any polarmount from a offset dish do the job?,also polarmount has to be strong and robust as its a heavey dish the fibre glass cm 1.8m.

Stick a request in the 'wanted' section, you might strike lucky.

There have been a couple of the early 1.8-2.4m offset dishes on this thread before now, whose ironmongery would take less modification than say a prime focus design if you take a risk and are prepared to pay for the carriage.

How good is your welding technique ?

Interesting 40cm system, BIN and collect.

Whilst it is designed for a wide range of prime focus reflectors, once an adapter is built that fits the front end the following quality polarmount would easily cope with the weight of a 1.8m Channel Master.

hi channel hopper i actually have that irte polarmount here on a 1.2m irte dish i know longer use,when you say a adaptor built that fits the front end can you give me more info please.
do you mean i would need to extend the declination on the irte mount for it to work with my cm 1.8m offset dish.

Nothing more, though I would advise on a counterweight to reduce the current required to drive the motor at low angle satellites

To modify an irte polar mount to accept another make of dish you need to fabricate a metal frame that can fit onto the irte polar mount and also act as a frame for the other dish type to be bolted on to. The metal frame acts as an interface between the irte polar mount and the non irte dish.

Some time ago I created a simple frame from some steel box section to mount a Precision satellite dish onto an irte polar mount. Normally, it would not be possible to bolt a Precision dish onto an irte polar mount as the mounting fixings are different. The frame I created out of steel box section acted as an interface between the satellite dish and the irte polar mount.

I also made a modification to the declination adjustment to allow for a fine tune threaded rod adjustment to the declination. I have attached some pictures of the frame construction and declination modification below.

In theory, you could create a similar type of frame to bolt a 1.8m chanel master dish onto an irte polar mount but with 4 appropriately distributed bolt holes for securing the dish.
I am not sure how well the modifications would work for a channel master 1.8m dish. If you can source an original polar mount for the channel master I would recommend that as the way to go.
The bearings on the irte polar mount version that I did the modification on were moderate quality and I was not impressed with them.

He needs to increase the range of the declination angle to match the offset of the dish.

This would not help in this situation as you need to have an extended declination adjustment of 108mm.

 

[Channel Hopper]

He needs to increase the range of the declination angle to match the offset of the dish.

All that is required is a 'V' or wedge that has the same angle as the Channel Master reflector offset. The Superjack 1224 has a similar design option to allow operation with non prime focus dishes.

The front end of the IRTE polar mount with four bolt holes is more than adequate to hold the weight of the dish and ironmongery securely.
