antenna is in, shack was delivered today. the antenna is fatter and lighter that I thought it would be but I think I can put the 7/8 right in to it w/o any problems.

on a sad note the gentleman who was going to help and teach me to climb the tree properly lost his wife today. we had just seen them on Thursday to discuss the game plan for doing this project. it was like getting hit in the head w/bat.

I may have to make other arrangements.

weather wasn't too cooperative this week but I managed to get a few things done.

layed out where and how I want things to sit, bolted the rack to the floor, put the antenna, pipe and mounts together. checked the length of the cable I have (29M,95'). I also had the shed co move the unit from the bottom of my driveway to the top where it was suppose to be put in the first place. still waiting on some grounding equipment so I haven't punched the hole for the feed through yet.

antenna was mounted into the tree yesterday. man what a job, took 8hrs to trim top and mount , pull and secure the cable. will post what pics I have later. I was pretty on about the height measured from base to the bottom hole for the mount was 74' , +10 for the pipe and the antenna is 78" over that.

I didn't get too many pics of the process. the gentleman who did the climbing did all the work  from trimming to the mounting of the antenna. I found it very difficult not being the one up in the air doing the work. it is also the first time I have ever hoisted an antenna whole w/cable attached to it.

on a side note I was amazed at how little the tree moved compared to a tower.

I used a test channel at 100W to check the SWR reflected power was 0.8W. I expect pretty good coverage out of this. will do further field testing w/genset and the repeater over the next couple of weeks.

You are a mad scientist, in a good way.  Great Job so far!   That shed should give you a nice surface and angle to mount the solar panels.

I've been thinking about an off grid repeater. Probably going to use a HT1000 (COR isn't hard to pull off of one) as the receiver and a mobile turned down somewhere between 10-20Which for the transmitter. Probably use an MSP430 as a controller. If I can get the site I want...should be a nice little setup.

Basically the same setup for a portable repeater I've been working on...just designed to be self sustaining.

hard line protected from anything that may crush it. still need to be secured a little better though.

still need some minor hardware and items to secure the shack better.

12 foot chain link with razor wire is always good.... ;)

I vote for electrification, too! 50 kV, no less! John can install a few solar panels to provide power and make the project more interesting. :D

By the way, John, wouldn't it be even better to bury the line as it runs between the foot of the tree and your shack, or would that be overkill in this particular situation? I don't know what sort of cable run you've got, in terms of actual physical distance, between the tree and the shack. And I guess that this is all happening on your own private property, but I think that we probably all know how destructive kids can sometimes be. Some of them might find the sight of that pipe running down the side of the tree to be of irresistible interest, if you know what I mean.

Around my area burying hardline or coax is not a good idea because the frost line in this area is at just about 6-1/2 feet. Unless the cable is inside 1-3/4 inch conduit there will be expanding and contracting of frozen ground in November and in March and cable for communications gets cut up, so it is just not run underground here.  In John's area, I don't believe that the frost line is as deep as it is here, but still exists.  I have heard that running even the best transmission line inside thick wall electrical conduit can create some really wild SWR's.... Never had that experience personally, but it may affect the inductance component of the cable and result in an impedance change.

Thanks for the information, gentlemen, I understand better now, and best of luck with the project John!

 

Regards,

 

Frank.

We have between 270 and 310 days of sunshine each year here in Albuquerque. The research I've done shows this to be an excellent area as we rarely have more than a week of snow each year. 

 

In a related area (converting a 1973 Toyota Hilux to all electric drive) I've found Optima batteries to be without equal. Yes their Yellow Top  deep cycle batteries are pricy.  I have one used as SLI on my 1985 Jaguar 5.7L. It spins the starter better than anything else I've seen.

JohnE - this looks awesome!  I wish i could find a group of guys willing to build something like this with me near my home in NJ.

I've been trying to rack down a diesel Hilux state side for years for a ranch pickup...near impossible to find without spending a bunch of cash. 

 

I ran an optima Yellow top in my XJ...only battery I've ever had that outlasted the warranty. After 8 years sub-zero temperatures, excess vibration, extreme heat (never getting cooler than 100 degrees for several weeks straight) it finally gave out. Currently trying Autozone's AGM in place.

it's been a while so here is what has gone on in the last yr.

I decided to pull the 1K feet of electric to it as the experimentation w/solar failed miserably over the summer. the winter will only make it worse.

there are now 3 legs of #6 going from my main panel to a sub panel in the shed. I have 2 circuits w/one duplex outlet each.

I am in the process of insulating it for the winter so as to keep it relatively warm or a least above freezing. I figure a 100W bulb should do the job.

pics to follow

on technical note my current draw w/battery chargers and transmitter on is under 3A AC w/voltage drop of only 1V
