2m70cm Dual Band Half-Wave Flower Pot Antenna The idea The half wave 2M version of the Flower Pot antenna is easily modified to a dual band antenna for operation on a band that is the approximate third harmonic of the fundamental resonance. The antennas will be switched on to the main feedline coax by a remote antenna switch.

Ganho Da Antena Flower Pot Antena Baru

This results in the antenna operating with four half-waves in phase on 70cm and provides a theoretical antenna gain of 6dBd on 70.

Flower pot antenna pdf. Theoretically this should provide an antenna gain of 3dBd at 2m. Antenna is approximately a quarter wavelength but reduced due to the end effect of a wire antenna with an open end. The aim is to so how easy it is to build a simple working atenna for use on 2m 70cm and hopefully encourge you all to try it out on the bands This low cost aerial can be made for a single band or using the open sleeve technique with some aluminium.

If you want to build one of your own I Have made up a flowerpotpdf file that shows how I made it and some construction hints. The individual whips are encased in 34 PVC pipe to hide their identity and to look like supports for the Flowers that will be added to the pot when the antenna setup is finished. Operation on the third harmonic is achieved by using a sleeve technique so as to form quarter wave phasing sections at the higher frequency to end.

Its a simple 2M VHF70cm UHF dual bander built with minimal supplies - it only requires 1 metre of conduit and 2 metres of coax. Pot and was called a Flower Pot antenna because it could be disguised and put into a flower pot so that it was not obvious for any person who saw the antenna. 3212019 Half-Wave Flower Pot Antenna VK2ZOI.

The picture to the right is the flower pot antenna installed in its final location at the CONDO. It could be covered with some artificial foliage to make it more realistic.

Half-Wave Flower Pot Antenna The diagram below shows the basic arrangement of the 2m Half-Wave version of the antenna. Welcome About Flower Pots. A few years ago a made one of VK2ZOIs dual band flowerpot antennas.

692013 The first 2 meter antenna I built was a dual band copper cactus J-Pole. Flower Pot Dual Band Antenna. The diagram below shows the basic arrangement of the 2m Half-Wave version of the antenna.

The basic half wave version of the Flower Pot antenna can be readily modified to dual band the antenna for operation on a band that is the approximate third harmonic of the fundamental resonance. Peter made a simple dual band flower pot. The Single 58 version of the Flower Pot simply substitutes a 58 wave-length section for the top quarter wave of the basic half wave antenna design.

To construct the antenna first select a suitable length of grey 25mm conduit as a minimum 1m but if you make it longer you will have more room below the coil to attach to your antenna support. Half-Wave Flower Pot Antenna. The antenna is dual banded to operate on 70cm using the same sleeve technique as used on the dual-band basic Flower Pot.

It can be viewed by clicking on the file name. Here is a link to his webpage with instructions for making several of his designs. Subtract 5 for end effect.

Dual Band Half-Wave Flower Pot Antenna. I was surprised how well it worked and a few others tried it and found it worked very well. This would be a great product for you to build.

Operation on the third harmonic is achieved by using a sleeve technique so as to form quarter wave phasing sections at the higher frequency to end feed two half waves in phase at. The basic half wave version of the Flower Pot antenna can be readily modified to dual band the antenna for operation on a band that is the approximate third harmonic of the fundamental resonance. The arrangement is shown in the sketch below.

1182021 Glen Lyons VK4PK has provided the following design for a 6 meter flowerpot antenna. To construct the antenna first select a suitable length of grey 25mm conduit as a minimum 1m but if you make it longer you will have more room below the coil to attach to your antenna support. VK2ZOI Half-Wave Flower Pot Antenna.

According to The Fundamentals of Single Sideband published by Collins Radio Resonance occurs when a dipole antennas length is a half wave length or multiples thereof. 145MHz x 3 435MHz thats 2M to 70cm or VHF to UHF.
