Dear Topbanders,
seems I am lucky in next winter. It looks like I will get the ok for renting neighbours
horseground for cheap (mmmh.... cheap?....) during the dark months. Thats the
moment I am waiting for years now.
Well, only 2 Hektar, 20.000m² or 6 acres, but beside my garden, and for DL a great
deal!
Now, just talking with the former guy who rented it, there are some questions. Maybe he
will leave some outer Posts for Beverages, but we need to know which.
I have just made a GoogleEarth based drawing of the lot, and my backyard:

There you see my house at the middle, left. Just left of the small name "Jürgenstorf".
The red circle is my 26m vertical, surrounded with lot of copper as radials.
Scale is abt. 20m from center of vertical to garden fence.
I have read a lot last hours, specially the "low-band-bible" and Tom´s, W8JI Site.
According to that special hints I tried to fill that acre with a wire web, which hopefully will
work, but I am not sure.
I tried to cover all main directions, depend on distance. I also tried to face the Ant-angle
vs. length.
What is your experience, has someone tried such an Bev.-park b4?
- Fx (light blue) are Feed-Points for the Bevs
- deg and Area added, for DL
- possible length of Beverage below
- I respected Tom´s experience, Feedpoints (with ground-rods) several wire-heights
seperated. Bevs. will be 1 to 1.5m agl, Feedpoints more than 10m separated.
- On Crossing points (especially between F2/F5/F6 and F2/F4) the wires will be >0.3m
(1ft) apart others (Tom´s Site)
- Still not sure abt the wire I will use, here are some animals. Wire should be strong.
Might be another question.
- Soil is wet here, the first ground-water always (!) between 1m and 1.5m below ground
level.
- Ground-Rods will be 1.5m long copper
- Coax will be Belden 9907 (that one which is similar to RG58), longest run 200m.
Questions are, for 80m and 160m:
1. Will that rx-web work without interaction?
2. Will that work with my Tx-Vertical, or should I ground/flow some in case of rx/tx?
3. Do I miss some basic in my ideas, maybe easier or impssible ways to use that 2
Hektar for rx?
