Became a Consultant in the field of Process Control and Automation for the sawmill and mining industry, then branched out to Energy Monitoring and Power Management. Retired from that in 1992.
Back in those days I used to be Net Control for the Muskeg Net and I still have the call in list for the stations back then. We used the list to call each one of the stations in turn and when we got to the end of the list we would see if there were any other checkins.
My present station consists of an Icom 735,
Vector 500 Linear Amplifier.
Multiband Dipole at VE3DXG's place.
Frequency Wire element lengths Wire size
The above measurements are a good starting point, leave all elements longer than above and just wrap the excess wire back on itself on the ends until you are happy with the SWR, then tie a knot at the end and cut joff the extra wire. All insulators are PVC 1/2 inch water pipe cut to 4 inch lengths with 1 hole drilled in each end to accomodate the wire size. The lower element wire end is pushed through the hole and just knotted. The upper end of the insulator is slid so that there is a bit of a droop to the lower element, then just a couple of turns of electrical tape around the upper wire keeps it there. The center insulator can be any suitable material 3 inches by 5 inches with holes drilled 1 inch apart for each element on each side. All wire elements are connected together and soldered on each side, RG 58 coax is then connected to each side. This antenna is very broadbanded on all frequencies, no tuners required, just switch your rig from band to band, see below.... Reflected Power 80 & 75 Meters 3.510 --- 1.75 3.750 ---
.25 3.850 --- .55 3.950 --- 1.5
Many have tried building this antenna and have been successful, others have given up in desperation, however it does take a bit of patience as every adjustment you make has an effect on the other bands. The easiest way to make the adjustments is to string the entire assembly up about 6 or 7 feet above the ground, adjust the 75 meter first so that it is 1 to 1 at your favorite frequency, once you have that done, adjust the 40 meter portion the same way and continue doing the same until you get to 10 meters. Pull the antenna up to operating height and mark down the SWR across each band so you have a reference point to work from. Again do your adjustments from 75 meters down to 10 meters, but pull the antenna up to its operating height each time. Good Luck, Ted
My smallest experimental 40 Meter Antenna!
I had it on top of a 6 foot step ladder in the back yard and worked stations in Ontario, Quebec and the east coast! Not bad for something so simple. |
This was my first "Ham Station" in North Bay in 1960. Top ... SX99 Hallicrafters
Rcvr, Homebrew Plate Modulator for the DX40 (Everyone said I sounded like
a broadcast station, audio wise, after I built it and went on the air),
above it is the Heathkit SWR Bridge, top far right is the Speaker for the
NC240D National Rcvr (lower left), DX40 Heathkit transmitter is on the
lower right. To the left of it is the VFO and under the VFO is a Homebrew
Scope that was used for checking modulation.
Here is a photo taken in October 1948 at McKellar, Ontario. The car is
a 1935 Studebaker and the 19 Set just rested nicely on the bumper. I bought
the 19 set from a War Surplus store in Winnipeg, through an ad in the Old
Family Herald, a weekly newspaper as I recall. About 2 weeks after I received
it, I had a visit from the R.C.M.P wanting to know what use I was going
to put it to. I remember being rather intimidated by the visit. That is
my brother Niilo, VE3NSB who lives just south of Parry Sound. It took me
30 years to talk him into getting his license !
