A Reader’s CB Antenna Question

A reader’s question I wanted to post a readers CB antenna question and my response. So here goes… “I have my 70cm/2m Diamond antenna on my roof for my TYT 9800 and it works great, but I want to string a separate CB/SSB field antenna up into the very large trees in my yard to get the best reception I can get. I live on a hill, 600ft MSL but between me and the closest city. 15-20 miles away is a hill that is 760ft MSL. I have “cobra heads” and resistors, 50’ of 12GA Solid copper clad PE jacketed wire and a 42’ Beldon 8340 50 Ohm RG-58/U BNC… Read More

Getting your Amateur (Ham) License

Why should I care? There are many means of communications available to you in the everyday world including Cellular and Landline Telephones, SMS, Instant Messaging, Instagram, etc. But these require a certain amount of infrastructure which may not always be available in a disaster.  Radio however and specifically Amateur (Ham) Radio provides that last means of contact, “When all else fails”.

Building the Tiger Tail Antenna

“If you can make a dipole antenna, then you can make any antenna.” – NC Scout Background Your handheld radio has an antenna that is a quarter-wave “monopole”.  It’s not very efficient, but it’s a compromise for better portability and convenience. You can improve this by using a Tiger Tail (also known as a Rat Tail).  This is done by adding a counterpoise to your HT antenna, turning your monopole antenna to a dipole antenna.  This inexpensive and simply made extension will increase your transmission range and may increase your reception.  Because it is tuned you will need to create one for each of your commonly used frequencies. You can… Read More

Refurbishing Batteries With Lithium Ion Phosphate Cells. I bought some cheap Liitokala lithium ion phosphate cells from Aliexpress for my military TRC-372 radio to replace the dead NiCad cells. Whether this was a good choice, time will tell.

The Good, Better, Best Approach (to radio and to life)

Research Freeze Do you have this problem? You read, watch videos, and think about what is the perfect way to do something. Or try to find the perfect bit of gear….and never get the project done. I admit. I do this….a lot! I get research freeze. Or I hesitate and don’t learn the skills because of fear or embarrassment. I’m remembering a quote, “The perfect is the enemy of the good”. How many hobbies have you started and purchased expensive gear for? Do you still have that $1500 bike? Do you ride it every day? How many good things I have missed because of waiting for the perfect? Too many.… Read More
