do you just need one anchor?

One per umbella. umbrella post fits into the top of the anchor and there is a tightening screw to hold it steady.

One per umbrella. I used it on a fairly windy day and had a hard time keeping it in the ground. Everyone else at the beach that day was having the same trouble.

No Anchor, the instructions call for a 4x4x8 pressure treated post cemented in the ground. this piece slides over the post and secures to it. I'm sure you could work something over an existing post too.

I would start with just one. You can always add a second later, but I would be surprised if you need a second one.

Just one. It works for me because I have very limited space anyway. Take that into consideration for your needs.

You could but I would recommend using anchors depending on what you are using this item for.

I would say you will probably need three of these and they will need to be well anchored.

No, the unit is a single piece, you'll need to use the existing cables and linkage.

Yes it should be but also depends on where you will be using it(lake, or river). Different type of anchors work better in certain situations. Keep in mind wind can also play a factor if you are trying to anchor and stay in one spot.

I would think so. It is the best anchor system I have found without pouring concrete.

It comes with the anchor system, you do have to dig a deep hole but it is well worth it! Very happy with the system.

No. One is all that is required. If you install one on each side, you will have problems aligning them so they work in sync.

Yes. You slide the arms onto the vertical bar, so you could put only one if you wanted to.

If you buy this, and we're very glad we did, look at the last page of the manual where it talks about attaching the anchors. Gotta do this early on after the frame is together or you'll have a tough time later.

I don't think it needs one. We did not anchor ours and it never moved or tipped or anything like that.

A 10# mushroom anchor should be more than enough unless used in high wind conditions. Even a 5# weight would suffice in non wind and non current conditions.

Yes, it comes with an anchor kit so be sure to use it. When they swing it is definitely needed.

Tie one end off hard, rod rope through tensioner, so therefore you only need one.
