Here’s my dilemma:
I am a rookie homebrewer. My kit experience is good, but I have struggled to build direct from schematics. Part of it is my lack of ability to conceptualize the physical layout and part of my challenge is lack of building experience and mentoring.
Several of my antenna tuner projects seem to have a TON of hand capacitance effect. They are built in plastic cases, some from the Shack and some from the local surplus shops and hamfests. Most commercial tuners are built in metal cases and I wonder if that would eliminate the sensitivity to the tuning hand?
I have a couple metal enclosures I can use and a great ham friend sent me some thin copper with adhesive tape on the back. I am thinking of slapping some copper tape inside the plastic cases and see how it works.
So, I am putting it to the vote:
Which material should I build with?
- Metal case is the only way to go (79%, 11 Votes)
- Use the copper tape inside plastic case (14%, 2 Votes)
- Just use the plastic case (7%, 1 Votes)
- Give up and buy a commercial tuner (0%, 0 Votes)
Total Voters: 14
And for the record, the vote in the poll for best ham radio QTH in the US was won by West Virgina. Here is the top 5:
- West Virginia (17%, 11 Votes)
- Kansas (14%, 9 Votes)
- Texas (8%, 5 Votes)
- Hawaii (6%, 4 Votes)
- New Hampshire (5%, 3 Votes)
Thanks and 72,
