[TowerTalk] Best way to mount two LPDA on single mast

[Kevin Shea]

I do have the land(space for the  antennas, towers and crane to move around.
 
My current thinking is to have the assembled tower lifted into place either in one or two lifts.  The top section would have the rotator already mounted in the tower.
 
Also I will have at least one professional tower guy when we rig and hoist everything up.  He knows safety and rigging but not setups quite like this.
 
Thanks for steps idea as well as the lanyard reference.

If you have the space lift the big antenna with the mast , the most important here if you have the LAND to
have the crane, tower and antenna moving around to make the installation.

DO NOT DRILL THE MAST,  Buy the Steps or  make your own steps  with muffler clamps or the DXE type
are just a piece of thick aluminum angle , channel  or Steel angle,  double clamp per step are needed

An adjustable lanyard   3 ft  and /or  complemented short lanyar for  rebar with a gorilla hook  to keep you in place like this

But if you hire a professional antenna installer he will solve all those problems for you, most recommended

Hi,
 
I am putting up an 80' self supporting tower (AN Wireless HDD-80). I will be using 2" chrome moly mast with ~ 10 ft of mast above the top of the tower.  To this mast I am planning on mounting a 7-30Mhz, 14 element LPDA and above it approx. at the top (8' separation) a 50-1300 MHz LPDA both from Tennadyne.
 
While I have many questions the ones here I am seeking answers for are: 
 
Should I lift the antennas already mounted on the mast and lower the entire assembly into the tower and rotator, or should I have the mast already attached to the rotator and lift (by crane) the antennas and mount them to the mast?
 
If the second option  is the chosen method how do I attach the upper antenna (I am tall but not ten feet tall)?  Do I need to drill into the mast and place steps into it? 
 
Finally, are there any other approaches I should be
 considering?
 
Thanks!
