1/2 λ antenna for 50MHz FM by JA1HWO

3-band whip antenna 144MHz, 430MHz & 50MHz by JA1HWO

50MHz 1/2 Wave Vertical Antenna by ON6MU
A much better type of antenna then a simple quatre wave and that has more gain is the 1/2 wavelength vertical. We know that the impedance of the 1/2 dipole is 70 Ohms when we attach the coax in the middle, but what if we were to attach our coax directly to the end?

5/8 vertical groundplane antenna for 50MHz by ON6MU

50MHz-Lambda/2-Vertical by DK7ZB
This antenna is very useful for receiving or scanning purposes, but you can use it for transmitting, too. It is 2,94m long and has a pi-configuration (Collins-Filter) for the matching.

6 Meter 5/8 Wave Vertical Antenna by G3JVL
The G3JVL 6 Meter ground plane vertical is a compact antenna that is ideal for portable operations. If needed, it can be disassembled into a very small bundle no longer than the longest element.

6 Meter 50 MHz Squalo Antenna by PA9T
Al langere tijd zat ik er over te denken om actief te worden op 50 MHz / 6 meter. Enerzijds omdat de hoeveelheid QRM thuis ervoor zorgde dat HF steeds minder goed werkbaar werd, anderzijds omdat ik het leuk vind om zo nu en dan weer eens te wisselen naar een nieuwe band.

6m omni-directional antenna by DL1GSJ
The design follows the idea of the so called "CobWebb-Antenna" for the high frequent shortwave bands. The basic concept of this idea appears to be a folded dipole made of twin-lead which is then bend in a circle of rectangle.

A 6m J-Pole Antenna using Ribbon Cable by G4AON
There are many of the popular J-Pole antennas described on the Internet, most are either ribbon cable antennas for the 2m band, or quite elaborate copper/aluminium tube versions for 6 metres. I was unable to find a 6m ribbon cable one, so I set about making one.

Antenne halo Sur 50MHz de F6CHT
Cette antenne n'as pas la prétention de rivaliser avec une beam mais elle m'a permis de réaliser de nombreux contacts depuis le dep 56 en france et sur l'europe ,la conception est anglaise.

Halo for 6 meters band by IW5EDI
This antenna maintains good omni-directional horizontal polarization. Basically the antenna is a half wave dipole bent into a circle,BUT shorter than a dipole for this frequency.

Home Brew 6M Halo by W3DHJ
This is the 'Jones version' of the Lawn Chair 6M Halo as viewed through the rear window of the mobile. Ain't that just the sexiest thing you've ever seen on the outside of a vehicle?

Omni-directional mixed polarisation antenna for 50MHz & 70MHz by G8JNJ
This is a simple 'Halo & Stub' antenna which provides an omni-directional radiation pattern with mixed polarisation, which I built for use with the SUWS WEB SDR.

Simple 50MHz-J-Pole-Antenna by DK7ZB
This J-Pole is mounted on a fishing rod. The radiator L1 is an isolated copper-wire with a length of 281,5 cm (with not-insulated wire about 1-2% longer!). The quarter-wave matching sector L2 is made with 450-Ohm-Wireman-cable (length 133cm).

Slot-Cube Antenna for 6 Meters by W6NBC
In the January 2019 issue of QST, I introduced the slot-cube, a remark-ably small 2-meter base station antenna, with similar gain to a J-pole, and, like the popular homebrew ver-sion, soldered together from 1⁄2-inch copper water pipe.

Squalo antenna for 6m by PA3HCM
...the “Squalo” antenna, or square halo. In fact, it’s just a square folded dipole. It radiates in all directions, with -4dB gain on the sides (compared to the front and back side).

The 6m Halo Antenna by KK5JY
he antenna is nothing more than a square loop of wire, approximately 30" (or ~76cm) per side. The loop is fed in the middle of one side, and the opposite side to the feed point has a gap in it. The result is a dipole antenna bent into the shape of a square, with one side of the square being slightly longer than λ / 8.
