This week, we're looking at a few interesting builds, from compact multiband solutions to specific band optimizations. There's a solid 50-watt amplifier project for the HF bands, something that comes up often for those needing a bit more punch without breaking the bank. We also have a couple of vertical antenna designs, one covering multiple bands and another specifically for 20 meters, which is always a popular choice for portable work. For those running an Icom IC-705, there are some practical insights into maximizing its potential in the field. And for stealth operations, a window loop antenna for 20 meters offers a clever approach. These selections should provide some good food for thought for anyone considering their next antenna project or looking to refine their portable setup.
