Multi-band Dipole's
Spi-Ro's Multi-Band Antennas Containing additional antenna traps, these models are easier for your radio to tune in to, and they see more of the bands
Other Multi-band Antennas
There is an obvious radiation hazard when using this type of antenna. Four pairs of traps would be required for a 5 band dipole.
Terminated Folded Dipole Antenna
The Terminated Folded Dipole antenna has been around a long time and has gained Trap dipoles, multiband verticals, and any system that has high SWR on
An Attic Coaxial-Cable Trap Dipole for 10, 15, 20, 30, 40, and 80
After consideration of the alternatives, I chose to construct a trap dipole antenna in my attic using coaxial-cable traps. I desired multiband capability,

An Updated Version of the G5RV Multiband Dipole
The July 1958 edition of the RSGB Bulletin contained an article by Louis Varney G5RV on a novel multiband dipole which did not require traps. Figure 1 (below) shows the antenna, later to become known universally as the ‘G5RV’.
All Band Antenna Solution
All I really need now is a multiband dipole (inverted-vee) for 80, 75, 40, Since I already have the 40 meter traps, all I need to build is the 30 meter two band beam mounted on the second mast which now holds a vertical antenna.
More Multiband Antenna Notes
One reason for the interest in multiband antennas is that I once had a very nice multiband It used a non-resonant dipole, open wire line, and an antenna tuner. Trap dipoles, windom dipoles, and multiple dipoles off one feedline.
Another All Band Vertical
make a multiband vertical by simply taking half of my 80/40 meter trap dipole The main difference in utility between the trap vertical and this is the trap acts as an automatic switch disconnecting sections of the antenna
Multiband Antennas
Another all-band antenna scheme is the simple 80/40 meter trap dipole. This antenna is driven with coax and has greater losses than open wire line but it can be used on all bands with SWR less than 3:1 and does not require an antenna

40m Beam
Now we have a balanced feed, multi band, vertical dipole that can be used on 40 through 10 meters with an antenna tuner. On 10 meters it is 3/4 wavelength and should provide a radiation angle of 7 to 30 degrees as well as some gain over
