Here is one other possibility... You could mount a small dish in the tree,
and direct it to the water tower. Regarding cable loss, by placing a small
USB WIFI remote at the focus, and then running a USB cable, the losses could
then be managible. Otherwise, it will take some hefty coax to minimize the
loss. Use of a small dish directed at the water tower could also work if
you have decent line of sight. Trouble is, that dishes have a significant
wind load.
There is also the possibility of using the tree and mounting a small yagi
aimed at the tree - unfortunaltely, it will probably change directions
everytime the wind blew.
You MAY be able to get away with not having to put a mast up at all. Using
a laptop, monitor the signal levels with a suitable antenna aimed at the
tower. You may be able to use a small tripod or equal mounted in the
yard.... a small yagi suitable for this frequency would certainly
work....you may be able to get enough signal thru the trees that you
wouldn't have to go to extremes....
Try some simple stuff first. I have a 6' dish in my attic, with a USB
network adapter at the focus - and I can get wifi signals from all over the
neighborhood

Subject: Re: [TowerTalk] Internet Antenna Elevation
All
Thanks for the replies so far questions have bee asked, so here are
my answers.
1) why not get DSL, Hughes.Net, mobile phone digital
The local pop density is 7 people per sqr mile so ...
DSL - I am right on the edge of the phone company service area - the
other side of the street is a different phone company ( if there were any
houses there ) so that have almost no interest in providing DSL service
Hughes Net - this is my current ISP. Unfortunately though the peak
bandwidth does approach the 1.5Mb/s service I pay for the long term average
is about 5.1kb/s. Also as their core network is not IP there is huge packet
fragmentation on the link. Lastly is the sat delay, about 0.25s per trip up
and back. When you have to have that delay on a V.P.N. , whilst dealing
with real time application, is it VERY slow.
Wild Blue - ATM, better for handling IP, however still Sat. delay.
Digital mobile phone - I am outside the core digital coverage are -
analog only out here
2) Tree grow.
Excellent point. The local trees are well established, I am in farm
land, so large trees are not encouraged as they suck too much water and
nutrient. The local landscape hasn't changed very much in 50 years. I was
planning on allowing a 10' clearance.
3) Cable loss to the antenna
The transmitter/receiver and antenna are built as one unit. I
believe it has an Ethernet interface, and is power by power over Ethernet.
4) ISP install
The ISP has only been offering the service for 6 months, and they
are not very experienced. They have only ever installed on eve mounted
antennas. They are keen to learn, but.. I want to make sure that what they
do is correct!
5) My employer pays..
They already do, $25 a month, installation is my problem.
6) Rigging it.
My hobby (passion) is sailing. I have worked in boat yards and
rigged many a mast. I figure loading are likely similar.
My question
As no one is suggesting anything other than a roof guyed pole, what material
should it be made out of?
Aluminum?
Glass fiber?
Steel Tubing?
Could I get way with water pipe?
All advice is more than welcome!
Many thanks
Brian
