Half-Wave Flower Pot Antenna The diagram below shows the basic arrangement of the 2m Half-Wave version of the antenna. The problem Im having is that my SWR meter reads about 31 across the band with the flower pot antenna.

Homebrew 144 Mhz Coaxial Dipole Antenna Flower Pot By Andrew Vk1ad Dipole Antenna Ham Radio Antenna Ham Radio

The antenna is dual.

2m flower pot antenna. 2m Single 58 Flower Pot Construction of the Single 58 whilst a little more involved than the basic half-wave antenna is again fairly simple. Electrically the antenna consists of two half wave elements at 2m stacked one above the other. A piece of coax in the middle inserts a half wavelength phase shift to make the second half radiate effectively.

Flowepot Antenna Build Clovis Amateur Radio Pioneers Carp - Check out our floating flower pot selection for the very. There are two possible explanations as to how. 145MHz x 3 435MHz thats 2M to 70cm or VHF to UHF The modification involves placing a coax phasing sleeve of aluminium foil around the.

My 6 Meter Flowerpot Antenna De s i gn I ns pi r ati on To those who have gone before I follow in your footsteps and try to add a little more to the understainding of the flowerpot. Note size of tube and turns on choke altered to uk tube size Someone asked me how much power the Flowerpot will take. Me doing a talk about the flowerpot antennas and halfwave endfeds at Huntingdon Radio Club.

You may need a guying ring a guy ropes for two or more extensions. If you need a compact nearly invisible VHFUHF antenna for your ham shack then try this Flower Pot design from Mike M0MSN. HAM Radio Antenna the Flower Pot Antenna a Stealth Antenna that you can hide in a plant pot and cover with plastic flowers and leaves No one would ever k.

I was surprised how well it worked and a few others tried it and found it worked very well. From the top of the co-ax measure off an approximate 58λ distance to locate the position of the feed point. After a little research I found an article that says it could be a problem with a bad ground plane but I though flower pots didnt require a ground.

Ive found a. 2m flower pot antenna center frequency 145250 MHz. Mike does an excellent job of taking us through the design construction and testing process for this remarkably simple antenna.

Place the guying ring over the top T-piece below the 9T choke. The ZOI Flowerpot is an end-fed half wave antenna for 2m made from nothing more than RG58 coax and 25mm PVC pipe. I had decent success building a 2m dipole and decided to give a 2m flower pot antenna a try.

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. To elevate the antenna add additional 1 metre pipe extensions as required. The design is by John VK2ZOI who has excellent documentation and a step-by-step construction guide on his website here.

9 turn choke on a 27 mm diameter form brass terminal block to support the weight of the antenna against a section of cutting board made as a mounting block. 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. Experimental Dual Band High Gain Flower Pot Antenna.

The diagram below shows the basic arrangement of the 2m Half-Wave version of the antenna. 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. Experimental Dual Band High Gain Flower Pot Antenna - Flower pot antenna perfect stealth antenna for 2m70cm.

From the top of the co-ax measure off an approximate 58λ distance to locate the position of the feed point. At 70cm each radiating element is one-and-a-half wavelengths and a foil outer makes the whole behave as four stacked half wavelengths. 584x1045 px Flower Pot Antenna Get Out Of The Radio Shack And Live Life - If you would like to repeat my experiment you will first need a big plastic flower pot around 70cm high 60 top diameter and 30 cm base diameter.

This experimental version is an extension of the basic Half Wave Flower Pot Antenna. Bauanleitung am Anfang verlinkt. Theoretically this should provide an antenna gain of 3dBd at 2m.

VK2ZOI Flower Pot Antennas for 6 2 metres by John Morrissey VK3ZRX. Flower Pot Antenna. Einfacher mechanisch endgespeister elektrisch mitte.

They are end fed coaxial dipoles with an interesting design to make them dual band and colinear for increased gain. With the addition of some tinfoil and sticktape it can double as a 70cm colinear. My version of the flowerpot sorry for the bad picture the antenna looks bent.

My father has run one using 100w on 2m with no problems. Sehr effektive Duobandantenne für 2m 70cm Amateurfunk Freenet Funk. 2m Single 58 Flower Pot Construction of the Single 58 whilst a little more involved than the basic half-wave antenna is again fairly simple.

Mike calls this antenna the perfect stealth antenna for 2m70cm. Portable 2m 1442 MHz 12 wave Coaxial Dipole mounted on a 1 metre extension. Suggestions For A 2m Roll Up Vertical Antenna Antennas Sota Reflector - Flower pot antenna perfect stealth antenna for 2m70cm podrobnee.

2m and 70cm FlowerPot Antenna. Inner conductor 455 mm and braid section 445 mm. 2m Half-Wave antenna Half-Wave Flower Pot Antenna.

Here is a link to his webpage with instructions for making several of his designs. A few years ago a made one of VK2ZOIs dual band flowerpot antennas. Higher gain is achieved by adding an additional half wave element at the fundamental frequency 2m coupled by a half wave phasing line to drive both half-waves in phase.
