SUBJECT: Field Day Antennas & Equipment. Part one
This is an eight part series and will conclude in April so that anyone
building these antennas or preparing for Field Day will have enough time.
FIELD DAY OVERVIEW:
There are many stories from field day events that new amateurs hear from
rain,wind,and rotten luck to the day the team made the top 10% in the class.
Field day is not a contest but it is hard to tell with some clubs or groups.
For point chasers,total HF QRP CW will bring in the big points. Of course,
excellent antennas are a must to make the QRP CW work in a sea of Amateurs.
There so many combos of point gathering that it could make your head spin.
One year I made a full size 40m 2ele beam and under poor conditions we
acked
up over 800 points on SSB alone at 100w. CW pulled in another 600 which was
over 40% of our total score. We had the E.F.Hutton station on 40m.
When our station talked everyone listened. BTW,it took two people to move
he
beam to a new bearing. :) Field Day is actually an event to see just how well
amateurs can put together an emergency communications field station and make
as many contacts as possible in a twenty-four hour period.
Huricane Andrew taught us the value of Field Day here in Florida.
So when you get out to participate in Field Day, think of what it would be
like to have no commercial power,little or no water,food,cover,and help.
It's just you and your ham friends providing the only local communications
link to the rest of the USA. When disaster happens know one knows the date in
advance. So keep these designs and ideas and prepare now.
Keep them in a kit that you can grab in a moments notice.
When disaster strikes, you're ready! As for the Field Day event,all you'll
have to do is show up with your kit.

=========================================
EQUIPMENT
Transceivers
o 2m (144-148){All mode & FM} [Mobiles,HTs]
o PACKET with laptop & software
o Simplex operation
o HTs for local comm at the site
o Satellite work
o HF (80/75m, 40m, 20m, 15m, 10m) [DC powered rigs]
*CB mobiles for the real McCoy-Not everyone is a ham when disaster happens.
o Hi VHF and UHF for SAT work or simplex
Receivers
o Scanners for local emergency reception
o AM/FM Commercial band (540-1610 kHz,88-108 MHz)
o DC powered Television.
Gen HF
o Tuners
o SWR bridge
Power
o Batteries - deep cycle 12Vdc
(trolling motor type or the type used in golf carts)
o Solar Cells for recharging batteries
o Small generators ( don't forget the fuel )
o Battery chargers to operator off the generators
o Power supplies to operate off the generators
o Wind generators (pray for a good wind which usually comes with the rain)
o Large generator (if possible)
Supports
o Crank-up towers
o Push-up masts
o Sling shot and/or bow and arrow,fishing line
(There maybe a tree or pole handy)
o Tower sections (Like Rohn 20/25)
Coax (stick with coax for this event unless you have a clear shot to the
ig)
o Jumpers
o RF runs (that actually reach the antenna without moving the rig.
Misc
o Safety Belt
o Rain coat
o First Aid kit
o Water
o Packaged,ready-to-eat food
o Gum
o A hat and bandana (sun and sweat) or prepare for cold weather for the
real McCoy.
o Toilet paper (sometimes lots of it because no one else remembers)
o Pencil,notebook,and calculator(solar powered,when does a battery go

o Extention cords
o Soldering iron and solder
o Toolbag with the right tools this time :)
o Extra connectors (PL259 males,bullets,barrels,elbows,BNCs etc,etc.)
o Mosquito repellent (SLAP!! "Oh!,sorry Bob." A must!)
o Asprin or equal (For the 5 a.m. headache)
