Been a Ham since 1971 & my 1st call was WNØGZR & ASAP I upgraded to WBØGZR with Advanced Privileges. As you can see my Rig is a Kenwood setup & running a 1500 watts on CW, SSB, SSTV & FM on 10 meters.

My Heathkit set up in 1975
Tornado hit my tower in 1976 near Wellsville, Kansas
Restored this Heathkit SB-301-401 on 7/12/2009
The Kenwood gear has been replace with Yaesu gear seen in the picture below.
The Rig I using now is a Yaesu FT-2000 with the DMU-2000 & a Kenwood TL-922A AMP with an inverted Vee 80/75 meters & a Hy-Gain Quad-Band EXP-14/Explorer 14 for 40-10 meters.
Took the 40 meter add on off the beam & fixed mounted it to the tower just below the beam
Tower is 65 feet on the North side & 100 feet on the South side
This was my old set up with the 40 meter on the beam
Picture 5 feet from the top off the tower that the antenna overlooks, you are looking due South.
I've had an Advanced Ham Radio License since 1971
My # is 199 - Dec. 30th 1974

Dipole / Inverted Vee Antenna Design
Formulas To Design Your Own Dipoles And Inverted Vees
Most hams are familar with the center fed, half wave dipoles and inverted vees that are very popular and easy to build. This formula will give you a starting point to make these antennas. There are several factors that affect the resonant frequency of any antenna. Some of these factors are: the height above ground, the diameter of the wire, nearby structures, the affects of other antennas in the area and even the conductivity of the soil.
If you've ever used some of the other antenna design programs you may realize that the formula for these types of antennas vary from about 476/f Mhz to 490/f MHz depending on the band and the height above ground!
Fortunately there is a
formula that can be used as a starting point in your design. For a center fed, wire dipole, this formula is 468 / frequency in megahertz. I've always cut the antenna a few inches longer which would allow me to trim the antenna in order to obtain a 1:1 match.
The inverted vee has always been about 3 - 5% shorter than a dipole at the same frequency. I used 4% as a constant in the calculation. You may change this value to any number that you like to use.
This page uses the standard formula, 468 / f MHz to calculate dipole lengths. You may change this number if you know of a better number to use as your starting point.

For you that have # 10 in your call sign like myself here's how you can make the Ø. Hold down the alt key down & type the code 0216 & release the alt key so the zero will appear.
Sent this to ARRL some time after 1975 & was in the 1982 Hints and Kinks
Below is a copy of a News Paper that a reporter wrote about what Hams do, just some idle info.

Here's what happens when the Squirrels leave their nuts in your Antenna
Took the 40 meter off so I'm back to Tri-band instead of Quad-band because of the weight & hard to keep it level. Also the squirrels were walking down the guy rope to get to the trap end cap.
Planning on putting the 40 meter antenna back up but as a fixed antenna to the tower, just waiting on parts.
