Thanks to everyone for the insightful comments. I will put the light bulb antenna on my list. Could an LED work? It should consume less power.
How come, though, there are so many comments from those who have no experience with the isotonic antenna, yet eHam is loaded with reviews from people who love them? Rick makes a good technical point I need to consider, but don’t understand why wHam has 78 reviews in the past 180 days give a 5-star average rating for the antenna, and 3.9-star average overall. I get that there have been disappointing novel antennas in the past. Anyone remember the can field antenna? I am looking for a good option for 20 m and have the coax run and waiting for the right selection. Open to ideas.
