HF Mobile-Things To Consider

If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=DD3_s4IIvDg This is post 2669 in a continuing series of simple ham radio antennas. Thanks to AE4VJ for this excellent introduction to HF mobile operations. The video discusses HF Mobile installations, grounding, and antenna options. Here are some comments from AE4VJ: This is NOT the "end-all be-all" for your mobile instillation as each will be different. This is to get you thinking and to bring attention to what you need to consider if you're interested in HF mobile. I don't like drilling holes where they aren't easily concealed and I like for things to look as factory as I can. These are the bigger challenges, but the biggest task is GROUNDING so this is they approach we take today. HF Mobile is CRAZY fun! You don't have to worry about running out of range of a repeater, you can get some WAS/DXCC Credits while on the road and, if y

Comparing a folded dipole antenna with a regular dipole

If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=dsyuotZyU_g This is post 2668 in a continuing series of simple ham radio antennas. Thanks to Kevin Loughin (KB9RLW) for this interesting antenna comparison. Kevin describes the advantages and disadvantages of each antenna design. Although the basic half-wavelength dipole will fulfill most daily requirements, you may want to build a folded dipole antenna, which exhibits a bit more bandwidth.  Kevin does an excellent job of explaining the construction practices and performance issues of both antennas. Here are a few comments from Kevin: I did some comparisons between a regular old wire dipole and a folded dipole made out of window line. Both cut for 20 meters and both installed similarly.

In this video, Gil of the "Radiopreppers.com" website analyzes the performance of the new 7 meter (22.9 ft) telescoping mast from Spiderbeam.  This antenna mast would be a welcome addition to your emergency "go-kit" or ARRL Field Day package. Here are some comments from Gil: Just like its big brother the Spiderbeam 12m mast, which I have been using for years and almost every time I operate portable, the much lighter and shorter (collapsed) 7m model does not disappoint. There is a 10m model also. Those two are perfect for traveling, much stronger than a fishing pole while still quite affordable. Thumbs up from me! Masts: h
