Stealth Indoor HF Radio Antenna

If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=5vq_4Kjb8Vo&ab_channel=joshbloom Here's a great HF indoor antenna from Josh Bloom.  With a little planning and approval from your significant other, a fully disguised antenna will help you cope with deed-restrictions on outdoor antennas. As Josh suggests, best performance will be reached using the various digital modes with low power.  Just remember the old saying, "A compromised antenna is better than no antenna." Here are some general comments from Josh: This is a very short video on my 10-75 meter wire antenna mounted inside my house due to my landlord. Works pretty well and very easy to do. I happen to be using JT8Call, but any digital mode would be fine. Voice could work, but make sure to keep the power reasonable. ----- Thanks for joining us today. Aloha es 73 de Russ (KH6JRM).  

40m Slopping Dipole vs Hustler 6BTV Antenna

In this video, Johnny (W5KV--"Signal Search") begins a new set of programs comparing a variety of amateur/ham radio antenns. The first program features a "battle" between a slopping dipole antenna and a ground-mounted Hustler 6BTV vertical antenna. Both antennas work as designed with the vertical requiring a good radial or counterpoise system to attain maximum efficiency. Johnny does a good job of showing both the advantages and disadvantages of these popular HF antennas. Here are a few comments from Johnny: Comparing a 40m sloping dipole against a Hustler 6BTV ground mount vertical antenna. This is the beginning of a new series of videos titled 'Antenna Battle Series!' Episode #1. If you have any ideas for antenna comparisons

In this video, Carl (2E0EZT) shows us how he operates under field conditions using an easily made half-wave end-fed antenna (EFHW). Here are some of Carl's general remarks: n this video I build an EFHW antenna and work portable ham radio overnight at the camping barn in the Peak District. The 49:1 unun was bought from ebay (seller no longer lists the item). Icom IC-7200 Bog standard power supply.

If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=HfspvTR-gCY&ab_channel=vk3ye This is post 2389 in a continuing series of simple ham radio antennas. Here's an interesting antenna "coupler" ("tuner") idea from Australian radio amateur Peter Parker (VK3YE).   According to Peter, this basic L-"tuner" doesn't require a variable capacitor. Here are some of Peter's comments: Variable capacitors can sometimes be hard to find. Especially during this time of lockdown with all hamfests cancelled. Described is a 1.8 to 18 MHz L-match antenna coupler that uses double sided fibreglass printed circuit board as a substitute. PS: Like these videos? Wish to support this channel?

Callum McCormick (M0MCS--the "DX Commander") has designed several successful HF antennas for radio amateurs. These antennas are price competitive with other brands, fairly easy to assemble and test, and produce excellent results. In this video, Callum takes us behind the scenes and shows us the design and testing procedures for his current "Nebula eXtreme Multiband HF Antenna." A thoroughly enjoyable look at antenna creation from start to finish. Here are some of Callum's comments: As I move to the "final push", I discuss the considerations including harmonics and practical problems involved with multiple elements and their tuning. We discuss element lengths, mechanical connections and hardware. Callum. #MNHR #YTB #HAMRAD

According to Peter, a little creativity and careful construction can help you get a decent HF signal from a very limited space, including a "small garden." Here's a general comment from Peter that may get those creative juices flowing: Sometimes the only solution for HF operation in small gardens is to go vertical. Here is some practical advice from 60 years experience! --- Thanks for joining us today. Aloha es 73 de Russ (KH6JRM).
