I haven't really tried many different positions for the DB-2. Its current position give us great signal strength for Télé-Québec. If you all really predict another winter of 50cm+ snow on our roof tops, then I'll have to go up there again and play with the height of the DB2. I'll give it a try and place it just under the DB-8, and determine if it interferes with the DB-8.

It doesn't have to snow as much as that for it to build up on a reflector. The next thing you know its buried even if there's only a couple of inches on the ground.

Here is what I have going on. Dual old school 4228's, CM Pre-amp all mounted at 85'.

Works pretty darned good!

Maxwedge: How did you assemble the tower? Is that a satellite dish at the top, or terrestrial internet?!

I had my local TV tower guy put it up. He is a retired North York Hydro linesman - hence the screw-in cable rods he used.
The man is 77 years old and a big fellow to boot. He just put it up a section at a time. He said he would climb anything as long as he knows it is sturdy and safe. I think the new tower and install was just below 2 grand. A good investment to get rid of my dial-up alone.

The dish on top is my Xplornet internet. I have no cable on my street so I wanted to be sure I had LOS to the their tower. I removed my old 40 foot tower and 4228 and added a second 4228 to put on my new tower. Yaamon rigged them up and the TV tower man put them up. Yaamon and I both stood by and watched because we both knew there was no way in He#^ we were going up there! :p

Funny as a kid, I used to run up my parents tower to fix the old flat cable with no fear.....now - not so much!

Awesome pics!

I thought for that height you had to go with the DMX towers, but now I know. Makes me want to add a section to mine- just got to find an old hydro guy in Hamilton. ;)

Cheers!

I thought the same thing - but with the proper anchorage and support a standard tower works great. That baby does not move - even in high winds.

Nice job, Maxwedge - between the hydro retiree and Yaamon that's a great team! What brand of tower is that? Not a Delhi from what I can tell of the top section.

Thanks Stampeder - All I did was supply the vision and the money!

I was lucky to be able to hide it (except for the top part) in that clump of trees.

I don't remember on the tower brand but I'll try and find out.

It performs very well - According to TVFool I shouldn't be getting a third of what I am receiving. I am not getting Ion though - probably could with a slight re-aim to the west but I don't want to bugger up any of the existing channels - so it is staying where it's at! Wife is very happy with the present lineup.

My setup is not anything impressive as an 85' tower but here it is. The antenna I have mounted and now aimed at buffalo is 3/4 of the width of my house. I am glad it is behind the house and pretty well hidden from the street.

I can't get them to show so here are the links

My new set-up with extended 91XG. Seeing a noticeable improvement on marginal stations. A real multipath killer.

mom2teens: Some of us have towers because we need them, unfortunately. If I could get away with a more affordable roof-top setup, I would. What impresses me is the ability to save money...and if your modest rig enables you that, then I am impressed. ;)

I'm curious though: I see a tower with a similar (CM Crossfire?) antenna, and the second antenna on your chimney. Is the tower mount not available to you? Or does it belong to another neighbour?

They are both mine. I have them aimed and am using 2 cable and have one connected to an RCA tuner and one to my tv because they are different and if I need to change the aiming I can't if I put them both on the tower. The rotor on the tower is shot and I would have to hire someone to fix so I opted for this option as a try since we were able to do the work so far ourselves. Not sure how happy I am with it other than I am getting 51 solid now. The rest is not working well possibly due to the crazy weather we have been having. I had blazing TV yesterday when I was aiming and when I got all the cables run it was all gone. And now with the ladder down and put away it will have to stay like that for the winter. :confused:

Ottawa/Orleans

Ripped my play structure temporary setup, now it's up on the roof with a slope tripod.
5 ft slope tripod
CM7777 (set for separates, FM trap enabled)
CM rotor
CM4228HD
Quad shield coax running to surge arrestor before it enters the house.

I hooked a cable to the VHF input and it's dangling near my soffit for a futur attic VHF antenna install.

Sadly, i think i'll need to go back up there to unscrew some of the 3 1/2 inch lag bolts which did not find a truss when I screwed, even though the stud finder was seeing something in the area. I may have missed by just a bit. A 2x4 backing should fix that.

I've been getting WNYF since last night, up to this afternoon, no breaks.

Nice pics.

You want to remove the black caps/covers in the centre of the bow ties- might give you a little more gain.

Good job - I hope the cops caught that dude in the blue toque who was trying to steal your tripod! :D

I've heard the suggestion before, but not yet heard of anyone removing these caps and seeing a difference on a 4228HD, so while I did consider it, I was not too keen on it, especially considering my hack measurements failed for my holy grail channel 18 and I had to revert the antenna back to stock. Now that it's up there, it may be hard for me to reach out this high... at this roof inclination !

Thanks for your input :D

I wonder if I could save myself a trip to the roof by unscrewing the lag bolts which didn't find a truss from the attic with a vise grip, then maybe tap on it when there is very little thread left, or make a pre-hole in my 2x4 backing so I can install the 2x4 in place with the bolt still slightly inside the attic. Upon arriving on the roof on a single visit, I could either discard the lag bolt for a new one, or just rescrew it back in, then waterproofing back done. One visit to the roof to unscrew the bolts avoided... ?

Right now I am only sure that the base went into a truss solid. 1 leg is surely not in a truss, and the 2nd leg I just don't know, my generous helper took care of this one.

Did you end up using the same shorter lags, or did you get longer ones?
