The Technical Mentoring and Elmering for Thursday, June 11th had 9 check-ins plus net control Dave (K6HWN). Discussions included Hayden’s (KK6OYV) fractional wave antenna construction progress and he’s promised to take pictures of the different stages and share them on his website when it’s up and running. Jim (KK6SXB) added to the conversation stating that there are magnetic loop and Faraday loop antennas but the fractional wave antenna gets its name because of the helically wound copper strapping that surrounds it.
I (K6FLD) had a question about why there were different types of amplifiers to consider when choosing one for the different ham bands we might operate on. Shackmaster (K6HWN) explained that for VHF and above its handed a little differently as it’s not practical to tune for the different bands. The amplifiers are made specific to the VHF/UHF bands and there’s just not that much need tune because the bands are relatively close in frequency. For HF 160-10 meters maybe even 6 meters you will need to tune your amplifier as often as your antenna for the bands. Also of you’re operating SSB the amplifier needs to be a linear amp, not so if just FM. You can listen to the audio archive of the net here.
