Thanks to Johnny ("Signal Search") for this introduction to portable field antennas.  Johnny does a great job of describing his favorite "take with you" HF antennas. His list includes a homemade "L-Dipole Antenna", a Sotabeam linked dipole, and an end-fed wire.  These antennas are easy to build, fairly inexpensive, and completely portable. With a little creativity, these antennas can be used in deed-restricted properties (HOA/CC&R)...easy to erect and disassemble. ----- Thanks for joining us today. Aloha es 73 de Russ (KH6JRM).  

Do small tuned counterpoises work with HF vertical antennas?

Thanks to Australian ham Peter Parker (VK3YE) for this unique elevated counterpoise system for his HF vertical antenna. According to Peter, the tuned counterpoise works fairly well.  You may want to use Peter's idea if your HF vertical has a poor ground radial system produced by limited space or deed restrictions. Of course, Peter's location on the ocean shore does a lot to enhance his signal. Here are a few comments from Peter: Long radials are a hassle with vertical antennas. Can short tuned counterpoises work? Find out as I try a dual band 17/20 metre antenna at the beach. ----- Thanks for joining us today. Aloha es 73 de Russ (KH6JRM).  

Which is better: Vertical or Dipole?

In this video, David Casler (KE0OG) tackles a decades-old question:  What antenna is better--Vertical or Dipole? Dave uses Antenna modeling soft wear (EZNEC+) to provide basic answers.  Of course, your results will vary, depending on height above ground, the purpose of the antenna (DX or local contacts), and geographical features, such as soil, trees, location, and weather. You could build both antennas and test the suggestions for yourself.  In my experience, an Inverted Vee antenna combines the advantages of both antennas.  But, as the old saying goes, "your mileage may vary."   Why not experiment and see what works for you?

Portable 40 meter Vertical Antenna Build

Thanks to Steve Palmer for this simple 40 meter vertical antenna project.  Although the antenna is designed for the 40 meter band, it can perform as well on the 15 meter band, using the third harmonic of the 40 meter band. This is an all-around basic antenna that will provide hours of fun and education on the ham bands.  Just take your time and be sure to install a ground radial system.   You can get multi-band performance by using 450 ohm ladder line and an antenna "tuner". ---- Thanks for joining us today.

If you need a simple, inexpensive Amateur/Ham Radio 2m/70cm antenna for portable or even home use, then this 2 meter vertical dipole antenna from Dave Tadlock (KG0ZZ) may be be what you need. With a few hours of your time and some parts costing between $20 and $40, you can have a high performance vertical dipole which can be fed by 50-ohm coaxial cable. Here is a comment from Dave: A simple ham radio 2 meter and 70 cm antenna for fixed or portable use. For details: http://www.amateurradio.bz/2m-70cm_ve... ----- Thanks for joining us today.

Non invasive mobile antenna mount for truck bed

Here are some of his comments: This is a non invasive friction mount for a truck bed. This antenna mount will work with any stud type antenna. Its been on my truck for just under a year and has shown absolutely no sign of fatigue. I have linex on my bed, so I didn't bother with paint protection as I didn't need it, However a piece of rubber between the bed rail and the clamp should protect the paint. I apologize for my hand getting in front of the camera, I don't have someone to hold the camera and manipulating the camera with one hand while giving demonstrations is fairly difficult, especially when climbing under a truck. :P ----- Thanks for joining us today.

80 Meter NVIS Antenna

Thanks to Tim Carter (W3ATB), we see just how easy it is to talk with your fellow hams using this ultra-simple antenna. This NVIS (near vertical incidence skyway) antenna is also a good HF emergency antenna, providing usable communications out to approximately 300 miles/486 kilometers.   Don't expect long-range DX contacts with a NVIS antenna.  But, for local, state, and regional HF communications, you can't beat this classic antenna design. ----- Thanks for joining us today.
