A dipole antenna is a radio antenna that can be made of aluminum, copper, and bronze tube with a center-fed driven element. It consists of two metal conductors of rod, oriented parallel and collinear with each other (in line with each other), with a small space between them.

The dipole antenna is a particularly important form of RF antenna which is very widely used for radio transmitting and receiving applications. The dipole is often used on its own as an RF antenna, but it also forms the essential element in many other types of RF antenna. As such it is the possibly the most important form of RF antenna.

A half-wave dipole antenna means the length of this dipole antenna is equal to a half-wavelength at the frequency of operation.

Why do we recommend this dipole antenna?


1).The half-wave dipole is very clear and easy for frequency adjustation, there are scales on the side bar of the antenna from which you can adjust the frequency from 88~108 by 1mhz stepping.

2).The dipole is a simple antenna to construct and use, and many of the calculations are quite straightforward.

3.)The radiation pattern and high gain of dipole:

Attention: When setting the antenna, the “Anode” end should be face up, “negetive electrode” should be face down

    Thanks Lanyue for sending me the info for your site. I intend to broadcast from a hillside toward the South on a lower fm freq. My question: should I use this adjustable 1/2 wave antenna, or use the other 1/2 wave antenna custom made for my frequency? I’m wondering if there is a difference in performance? It looks like there is very little in price difference.

    Thanks,

    Jim

      Hello Jim Jester

      I think you could use the dipole antenna in my website. The frequency could be adjusted .
      If you have any question .pls feel free to contact me .

      Hello Jim

      I think you could order the 1/2 wave dipole antenna kit because the frequency could be adjusted as you like .

    I have been planning on buying this kit for some time. Is the price still the same? Also, can you get me 100 ft. of high quality (mil spec) cable with attached connectors for the kit?

    Thanks Lanyue!

      Hi Jim
      I could offer you 15m cable with connectos for this kit .ok?
      my email is kitmanlaw@gmail.com

      Sincerely!
      lanyue

      • Jim Jester 2015/08/06 at 14:58:59

        That is ok, Lanyue. I can get additional cable somewhere else if needed. Thanks.

        Jim

    Why are there two buttons to click on PayPal for buying this kit?

    Jim

    • admin 2015/08/13 at 03:50:09

      Hello Jim Jester

      could you click the first one paypal button ? It is for one kit price.
      The second one is the price for 2kits

      Best Regards
      lanyue

      • Jim Jester 2015/10/13 at 12:28:01

        Yes, I will be buying one tomorrow. Please send the BNC cable for the antenna. I do not necessarily need the audio cable as I already have one.
