Flower Pot Antenna Gain

Flower pot antenna and wifi sleeve dipoles i am getting back into ham radio, inspired by the incredible response to the codec 2 project from the ham community. I have made quite a few of these antennas and they work very well.

A few years ago a made one of vk2zoi's dual band flowerpot antennas.

Flower pot antenna gain. Build your own 6db gain flower pot antenna from coax that you probably have laying around your house. Turn the flower pot over so the mouth of the pot is faced down. This resulted in an antenna with swr of about 1.0 on 146.52 mhz simplex, and 2.0 on 144 and 148 mhz.

Electronics projects diy electronics ham radio antenna wifi antenna radios hf radio radio frequency alternative energy home brewing. This will give you the cone shape of your hive. The arrangement is shown in the sketch below.

This project is very simple to build and requires an all plastic flower pot with plastic hanger for outdoor use on a. By all reports, its a beauty. The present invention is an artificial potted flower and plant television and radio antenna.

They are end fed coaxial dipoles with an interesting design to make them dual. The antenna is in the shape of a flower pot with flowers in it. The flower pot antenna *is* a half wave dipole, and is center fed, just as the 1/2 wave dipole shown in the video.

Experimental dual band high gain flower pot antenna this experimental version is an extension of the basic half wave flower pot antenna. When a ham sees an antenna, he sees a thing of beauty but to others an antenna may not seem so beautiful. That simply means that all directions have the same energy radiation, and are all equal to the average energy radiation.

I was surprised how well it worked and a few others tried it and found it worked very well. Its called a flower pot antenna because, the original antenna was cleverly disguised in a flower pot. The flowerpot works well as a scanner antenna for vhf and uhf listening.

The clever inventor of this antenna is a nsw amateur radio operator (vk2zoi) and the instructions to build this antenna are on his website.

Its called a flower pot antenna because, the original antenna was cleverly disguised in a flower pot. Add small black ovals for wings, black antenna, and of course eyes. In my home office, i had trouble listening to the local 2m repeater due to all the high speed digital kit i have.

The main category is antennas for 2 meters band that is about antenna projects for 144 mhz. 8 antenna gain (g) because an antenna is a passive device, the power radiated can not be greater than the input power. Antenna gain is expressed as a ra tio of the effective radiated output power (pout) to the input power (pin) the gain of an antenna is a measure of power transmitted relative

A very neat antenna for 2 and 70. Here is a link to his webpage with instructions for making several of his designs. Presented here are plans for an antenna that will be beautiful to all!

This link is listed in our web site directory since saturday may 21 2011, and till today flower pot antenna for 2 and 6 mt has been followed for a total of 2369 times. About flower pot antenna for 2 and 6 mt the resource is currently listed in dxzone.com in 2 categories. The arrangement is shown in the sketch below.

The base emulates a flower pot and the antenna ears resemble the stems and petals of flowers. 2m 144 mhz coaxial dipole or known elsewhere as a flower pot antenna. With the addition of some tinfoil and sticktape, it can double as a 70cm colinear.

Use your construction paper to craft some paper bees. Half of the fpa dipole is the 1/4 wave wire (center conductor of the coax), the other half of the dipole is the 1/4 wave of coax shield. Other suggestions were made at the time included making a fake patio umbrella but the name flower pot has stuck for the last 14 or so years.

Single 5/8 flower pot antenna. no gain can be expressed in linear terms like x1 (times 1). As i see it, the antenna works by having the signal travel through the.

An optional signal amplifier may be installed within the base for improving signal strength. 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). You can do this by creating a black paper circle and lining strips of yellow paper across the circle.

Experimental dual band high gain flower pot antenna. Mounting is up to you of course but relatively cheap and simple. Rigexpert 600 mhz antenna analyser vswr results.

This resulted in an antenna with swr of about 1.0 on 146.52 mhz simplex, and 2.0 on 144 and 148 mhz.
