Question about Actuators Specifications

[Vallenato]

What is the difference between "Inches measures" in Actuator specifications?
24V- 12 ", 24V-18", or 24V- 24"
If I get 24" means I will get more expansion when my dish move and Could I get More satellites in the arc than 12"?
I know that More big is more Heavy but is "worth " to have more Inches on the actuator to have more expansion?
I am looking the best actuator for my Sadoun 1.8 Mts antenna to get More satellites Posible
24V Can work with Gbox or Vbox positioner?
What "Cheaper" Brand you recommend to me?
Or redirect to me to read more about Actuators
Thanks

I don't think a 1.8m dish would require a 24" actuator, the dish manufacturer likely has recommendations for the actuator length. Maybe call Sadoun to get this info. Generally the longer the stroke the larger the dish it can handle. Most actuator motors will handle 36vdc but I know some are rated for 24v, I don't think it will be an issue, but best to get equipment that matches your installation; recommended actuator length and a positioner that matches the actuator's voltage or an actuator that matches the positioner voltage.

I have a 36V 24" Von Weiss actuator for my 3m antenna. Been working well but showing a bit of wear (play) lately. Will need some maintenance soon...

May be yes, may be no. It all depends on the dish mount geometry. A 12 inch may not move the dish from one mechanical 'end' to the other. Then again, a 24 inch may be capable of moving the dish past the mechanical 'ends'. Therefore, it would be imperative that the limit switch is set correctly

but is "worth " to have more Inches on the actuator to have more expansion?

It's been many times proved that 'more is better than too little.

24V Can work with Gbox or Vbox positioner?

Yes.
As to recommending a 'cheaper' brand, I can't and won't because I've been using my VonWeisse since the 80's. (22 of 24 inches used on my 10ft) Hypermegasat has a couple of powermax's on his site. They are cheaper than the HARL's at Sadoun, but they may be 'cheaper' and not 'live as long'? I couldn't tell you. No experience with either brand.
I suspect, but cannot find any confirmation, that an 18 inch will suffice on the Sadoun 6ft dish. Why not call and ask them what length is recommended?
((Off topic;FWIW- boy, I gotta learn to type faster, and with less errors. Cham, I started replying 7min before your post, and got it 'finalized' 6min after))

Thanks Brothers!!

Thanks Brothers!!

Vallenato, did you get a firm answer from Sadoun? I also suspect the 18" is more than enough for their 6ft dish, but 24" might be warranted, in case you might ever upgrade to a larger dish such as a 10 footer. You could then just move it over to the larger dish.

For me i can get most of the arc (30 to 135) with a 24" on my 6 ftr! a 18 or smaller would most certainly limit me to a smaller part of the arc.

Here's a link to a post on another forum (by me) on that nut replacement!
