Field Day Antennas and Kits: Part 4
Setup at a site can be easy or a nightmare. I'm sure even a simple wire
dipole has had it's day in the sun beating the amateurs 14 to 0.
Scope out your site first and note structures, cover, water, toilets,
etc. Take a friend and make extensive notes. Draw a layout of the site
and if possible, measure the distances where you plan to put your
antennas and equipment.
Here's an example: This site is at a park by a river.
1X tree
1[pavillion]
1T picnic table
[toilets] 2X tree 3X tree
4X tree
2[pavillion]
5X tree 6X tree
2T picnic table <- North
==========================================================
========================================================== river
Location state: New York
Looking at this site it can be seen that most of the contacts are
going to be west and south although some contacts will be east and
north. Your geographic location plays a big factor in you antenna
placement. This same site in Central Florida will have a different
lay-out. And the same site in Washington State will be different
again.
Look at the setup and make some notes on how you would setup the
following antennas and equipment:
10m two element yagi
15m two element yagi
20m aluminum dipole
40m Inverted Vee
80m Wire dipole
SAT setup
PACKET setup
Generators (2)
Food area
Public greeting area
You have three push-up masts and each coax is 70 feet for HF and 30 feet
for VHF/SAT. The distance between the pavillions is 75 feet.
Here's another site:
1X tree
[building] W water tower
L street light
2X tree [building]
3X tree
North --->
Location: Kansas
Use the same antennas as above except 40m is a wire dipole. 2X and 3X
are 120 feet apart.
