By all reports its a beauty.

Flower pot antenna. Place the bottom 1 metre pipe extension in a flower pot. The 58λ radiator uses a 02λ shorted. VK4PK 6m Flowerpot Antenna - V10.

They are great for portable and permanent installations as. That includes the upper radiator lower radiator also the length of the cable that will be wound on the PVC pipe. I have described on this website a number of VHFUHF antennae which have become known as the Flower Pot antennae.

They are end fed coaxial dipoles with an interesting design to make them dual band and. 4 Levede 13 Flower Holder Plant Stand Hanging Pot Basket Plant Garden Wall Storage. What is a flowerpot 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. Half of the FPA dipole is the 14 wave wire center conductor of the coax the other half of the dipole is the 14 wave of coax shield. Half-Wave Flower Pot Antenna 2M or 2m70cm Dual Band Image 1 the Basic VHF 2M Design This is the basic 2m Half-Wave antenna using grey 25mm conduit to build a Dual Bander with 70cm capability - Continue the steps from Page 4.

The ZOI Flowerpot is an end-fed half wave antenna for 2m made from nothing more than RG58 coax and 25mm PVC pipe. The single and dual band versions are cheap to make and perform well as long as you stick to the dimensions given. Double 58 Flower Pot Antenna Extension of the Single 58 and uses a 58λ element for both the top and bottom radiators.

My father Les G6SXB uses one when he goes caravaning so here it is the. This results in the antenna operating with four half-waves in phase on 70cm and provides a theoretical antenna gain of 6dBd on 70. The design objective is to produce a vertical antenna for the six meter band centered on 52Mhz with a.

The arrangement is shown in the sketch below. If you prefer the antenna to be centered at 14525 MHz change the two element lengths as follows. 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.

Single 58 Flower Pot Antenna Substitutes a 58 wave-length section for the top quarter wave of the basic half wave antenna design. 25mm Conduit Minimum 1metre. With the addition of some tinfoil and sticktape it can double as a 70cm colinear.

Dimensions shown are for a 1st build prototype from a concept drawing and have yet to be refined. Nylon line 500mm Al-foil. The design is by John VK2ZOI who has excellent documentation and a step-by-step construction guide on his website here.

Here is a link to his webpage with instructions for making several of his designs. Ive heard all sorts of answers to this question most of them completely wrong. A quarter wave aerial an end-fed aerial a coaxial ground plane aerial All incorrect.

I was surprised how well it worked and a few others tried it and found it worked very well. Single 58 Flower Pot Antenna. A flowerpot aerial is nothing more than a cleverly-fed half wave dipole.

Like most antennas mount the flowerpot high and clear they work well. Enjoy constructing your own version of the 2m coaxial dipole antenna known elsewhere in the radio amateur community for obvious reasons as a Flower Pot Antenna. A few years ago a made one of VK2ZOIs dual band flowerpot antennas.

2m and 70cm FlowerPot Antenna. The Coaxil Dipole Design was further developed as the Flowerpot Antenna by John Bishop VK2ZOI. Here we do not count the number of turns because it will vary depending on the diameter of the PVC pipe used to wind the cable.

A very neat antenna for 2 and 70. The flowerpot works well as a scanner antenna for VHF and UHF listening. The flower pot antenna IS a half wave dipole and is center fed just as the 12 wave dipole shown in the video.

Recently at the EMDRC working bee Bob VK3AIC EMDRC Committee Member created quite some interest when he brought in his latest project. 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 third harmonic.

Garden Sculpture Planter Rust 108x50cm. If you know how a dipole works then you know how a flowerpot aerial works. Have a look at John VK2ZOIs page for a bit of a history lesson.

We provide a no obligation free quote service subject to site inspection with no call out fee. This calculator is used to determine the length of each element of the flower pot antenna. Post Update 5 May 2019.

The ubiquitous Flowerpot antenna has been around since about 1993 but the origins go back to the mid 80s. Bob VK3AIC with his recently built flower pot antenna from VK2ZOIs site. The antenna is dual banded to operate on 70cm using the same sleeve technique as used on the dual-band basic Flower Pot.
