How To Set Up An Antenna For Ham Radio



How To Set Up Ham Radio Antenna 

This article will help you to understand the basics of antenna and how to place linear amplifier with swr meter and antenna.

The first thing you need to do is to find a good location for your antenna. You should make sure that it is not too close or too far from the transmitter. The best location for an antenna is in the middle of a clear area, away from any obstructions like trees, buildings, or hills.

The next step is to measure the SWR (standing wave ratio) of your antenna. This can be done by using a SWR meter which can be purchased at any electronics store or online. You should place the SWR meter on one side of your antenna and then move it around until you find the point where there is no signal coming through on the



The antenna is the most important part of a radio system. It is the device that converts the electromagnetic waves into electric signals. The antenna should be placed in a location where it can receive and transmit signals without any obstructions.

The swr meter is used to measure the amount of power being transmitted by an antenna. It should be placed near the antenna to get accurate readings.

A linear amplifier should be placed as close as possible to the antenna, but not too close or it will cause interference with other devices in your home or office.

The First Ham Radio Operator


Would you like to know, was the first Radio Amateur ?

Well let me tell you . 

The first radio amateur radio operator was a man named Reginald Fessenden. He was born in 1866 and died in 1932. He was an inventor and engineer who is best known for his work with the development of the first practical radio transmitter.

Reginald Fessenden was an electrician, chemist, and employee of Thomas Edison.

Fessenden's work with the development of the first practical radio transmitter led to him being called "the father of modern wireless."

Ham Radio Modes


The most common mode is voice communication, which is done by using a microphone and speaker to transmit and receive sound waves. Other modes include Morse code, which transmits messages in the form of short pulses of light; radioteletype (RTTY), which transmits messages in the form of long pulses of light; and various digital modes that transmit data over a radio wave.

Universal Case Blue Fitting Accessories

Here are some pictures which are being published so that our customers who have purchase the
Universal Case for fitting their Bitx 40 smd could follow the same process as we have not provided any building manual for the case.

So here is the lovely Blue case which has two stereo socket  connectors to be used as Mic/PTT or headphones in any configuration as desired as there are many ways of using the Mic And PTT pins, the way you like.  Like you could use one socket for PTT And Mic since it is a stereo socket and use other one for a headphone, so both purpose can be met,

If you plan to use a baofeng mic then the only problem is that the baofeng mic has two pins, the smaller pin may not fit in the stereo socket as the size will be large for it, on the other hand the big pin will fit okay, so you would need to find a smaller socket, which i could not outsource.

The 10K Linear Potentiometers  for Mic Gain And Audio Gain have to be mounted as in the picture, remember you need to enlarge the holes for both these Potentiometers  slightly with a tweezer so that the 10K LIN  slides into the hole, you may face a problem if you try to fit by turning it clockwise as it may bang with the other Potentiometer, so make it slide with enlarging the holes very slightly.

The stereo sockets also need to be mounted as shown in picture, we could have increased the gaping but then the chinese mic would not fit, so its a compromise.

I am using a Lu5DJV DDS in picture, you could use your DDS with the kit you got it will fit exactly the same way.

The Bitx 40 SMD pcb will be very well placed on the bottom case with ample space from all 4 sides of the case.

The SO239 Connector , Push to on switch And DC Supply and fuse holder all fit very well as in picture.   DC lead is also provided for connecting power to the transceiver.

The knobs can be changed if you have more colorful ones,

I will upload some more pictures soon for other models and colors, hope I have been able to
explain how to fit the accessories
