Default The big cel job

Just got a big job to install miles of pipe at The Merchandise Mart in Chicago. The prints are worthless. I've only been able to get info from the vendor that Ma Bell hired. We're pulling heliax cable to the antennas and I've been told 7 is the most I can expect to get through a 4". I know this is basic info, but any advice on this? Specifically, on pulling this cable that is about the size of 4/0.

I've got to cover 4.5 million square feet and have a working system by May 1.

What size cable, that stuff ranges form 1/4'' to 1 5/8'' We just got done running the 1 5/8'' up a 50 meter antenna and we got 2 per 4'' pipe x 4 pipes installed with no kinks.

If you are not experienced with running RF cables like Heliax bone up on it. I am sure they will be testing the cable and any damage/mishandling will show up.

True that. I've pulled exactly one in my career. I plan on lubing the hell out of it as it seems like a coax inside of a hula hoop casing.

Our crew will be responsible for pulling and the carrier will test, so yes, care must be taken.

I'm wondering about the pulling head. Basket?

Oh, there will be photos. Documentation requires reams of them. I'll post what I can.

i never used a basket. Just mule tape, and lots of clear, not yellow.

Also rolls and rolls of tape too.

are you sure you can put that many in a 4inch too?

oh, and for cutting it, you can use a flex cutter, or a flex knife. works great!

I might have some stuff i can send you as well to help you out. We just finished RF in school

Thanks for the offer! I was hoping the basket would help speed the process a little. Luckily, we don't have to terminate it. AT&T is doing all that.

Goose - so your company is doing just the physical install but no terminations or commissioning? Do you guys get many of these Distributed Antenna System jobs? If you guys are wanting to get into the terminations and head end work too instead of cell carriers doing it (so you can make some more money) PM me, that is what I do full time as of right now - partner/joint venture with other EC's to do initial site walks/initial survey/proper installation and terminating techniques/head end install and commissioning. If you are interested PM me.

That used to be true, but the zip was expanded. I don't know by how much.


The Merchandise Mart is the largest commercial building in North America. For anyone who is interested here's the wiki page. The building is pretty amazing.

Really interesting. Can't wait to see pictures of the job seems like real good work. I find work I have never done/do rarely is always fun to do.

There is one company that pretty much does all the install of the equipment, and ends.

Its not technically a union job. But any cables pulled, is.


I forget the name
