HF antennas suitable for emergency deployment
« on: May 02, 2023, 08:50:22 PM »
There are a few HF antennas that I would want for emergency deployment if other facilities were not available.


Having a quick-deploy antenna pole would make things much easier as any of the normal dipole, inverted-V, and similar wire antennas could be strung as long as there was a good elevated center support.


A home-made Yo-Yo antenna that is adjustable to different HF bands is well suited to this and can keep everything organized and much less likely to tangle. This antenna used to be available commercially but I cannot find them now. They are not difficult to build. Here is one simple method:

One of the 43' free-standing vertical HF poles using a remote or manual antenna tuner is another good choice. A commercial system, such as the MFJ 2990 43" 1.8MHz - 30MHz vertical antenna when used with the MFJ 998-RT 1.8MHz - 30MHz 1,500-watt remote antenna tuner. Other antenna tuners can be used with less power. There are additional parts that can be added to make installation easier and antenna efficiency increased.

MFJ-998RT, REMOTE AUTO TUNER, 1.5kW, 1.8-30 MHz | MFJ Enterprises Inc


Two other antennas with similar function are the KJ7U Larry's Antennas HD 6m-160m screwdriver antenna
HD 6-160 (kj7u.com) or the Hi-Q antennas [size=78%]Hi-Q-6/160 Antenna
