Flower Pot High Gain
The antenna is dual banded to operate on 70cm using the same sleeve technique as used on the dual-band basic Flower Pot. Pin on Amateur Ham Radio antennas.

It was kind of a paint to tape off so I got lazy and only did one side.
Flower pot high gain. This experimental version is an extension of the basic Half Wave Flower Pot Antenna. A very neat antenna for 2 and 70. Recently at the EMDRC working bee Bob VK3AIC EMDRC Committee Member created quite some interest when he brought in his latest project.
This results in the antenna. Theoretically this should provide an antenna gain of 3dBd at 2m. Of course you dont have to follow this verbatim but its a great rule of thumb for creating beautiful pots with a lot of visual interest.
Flower pot antenna gain. This experimental version is an extension of the basic Half Wave Flower Pot Antenna. 2m Construction 2m Single 58 Flower Pot.
However note that the Handbook indicates that in practice the Gain Sleeve antenna would realise about 25dBd. The diagram below shows the basic arrangement of the 2m Half-Wave version of the antenna. 2m Construction 2m Single 58 Flower Pot.
8 rows This experimental version is an extension of the basic Half Wave Flower Pot Antenna. Theoretically this should provide an antenna gain of 3dBd at 2m. 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.
There was also a medallion in the center of the pot on the front and back. Its called a Flower Pot Antenna because the original antenna was cleverly disguised in a flower pot. Theoretically this should provide an antenna gain of 3dBd at 2m.
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. For the height consider tall grasses and vertical reeds that can be placed toward the back of the arrangement. Have a look at John VK2ZOIs page for a bit of a history lesson.
The flowerpot works well as a scanner antenna for vhf and uhf listening. For me the top and bottom were gray and I liked that so I taped them off. 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 ubiquitous Flowerpot antenna has been around since about 1993 but the origins go back to the mid 80s. Prepping your Flower pots for paint. Bob VK3AIC with his recently built flower pot antenna from VK2ZOIs site.
However note that the Handbook indicates that in practice the Gain Sleeve antenna would realise about 25dBd. 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. Remember we use coaxial transmission line because among other reasons it confines what is.
By all reports its a beauty. 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. The effective radiating element length of the Single 58 Flower Pot is 78λ suggesting it would have somewhat less than 25dBd gain.
The VK2ZOI high gain dual-band Flowerpot Antenna. Im going to try this looks really good. The first thing you need to do is tape off any areas that you dont want to paint.
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. Half-Wave Flower Pot Antenna. The effective radiating element length of the Single 58 Flower Pot is 78λ suggesting it would have somewhat less than 25dBd gain.
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. The flower pot antenna IS a half wave dipole and is center fed just as the 12 wave dipole shown in the video. Ham Radio Antenna Wifi Antenna Electronics Projects Radios Hf Radio Dipole Antenna Big Data Technologies Radio Frequency Alternative Energy.
This experimental version is an extension of the basic Half Wave Flower Pot Antenna. Saved by Chris Ferguson. Its called a flower pot antenna because the original antenna was cleverly disguised in a flower pot.
This link is listed in our web site directory since saturday may 21 2011 and till today flower pot antenna. Theoretically this should provide an antenna gain of 3dBd at 2m. Bob mentioned that John VK2ZOI has some very.
Build your own 6db gain Flower Pot Antenna from coax that you probably have laying around your house. Presented here are plans for an antenna that will be beautiful to all. Experimental Dual Band High Gain Flower Pot Antenna.
The single and dual band versions are cheap to make and perform well as long as you stick to the dimensions given. Most beautiful flower pot arrangements follow a general height fill spill structure.
