I like to try different antennas of different designs at different locations. I have 30-acres undeveloped land for wire antennas (no towers). I am interested in these designs: Random wire End-fed Delta Loop Big loop Lazy H Trap dipoles Bazookas etc. coax fed 75 ohm coax fed balanced feedline all modes HF VHF UHF I am also interested in the phased Lazy H. I have 1:1, 4:1, and 9:1 baluns on hand and 14 guage to more lightweight wire intended for QRP operation. I have managed, so far, with MFJ Travel Tuner and MFJ Auto Tuner Extender. However, I have limited my antennas to dipole, fan dipole and purchased end fed. End Fed Scorecard: Radiowavz end fed - good eBay wire j-pole - bad I want to do better than 50-50 chance I will destroy the transceiver. I recently purchased a You Kits FG-01 antenna analyzer to find resonance and other frequencies of acceptable SWR on the antennas I already have, without having to carry an antenna tuner for portable operation. I thought that would be fun. It is not expendable $$$ I do not want to "pop" my FG-01. I think my next purchase will be the Bluetooth Mini60. I have a computer tablet. Expense is a constraint. I will have to learn how to use the information from that antenna analyzer. It is a SARK100 design. I think this is how to "gear up" for reasonably safe antenna construction or purchase, after having "burned" the 2-meter finals on my ICOM-2710H. I do not want to "burn" finals on my HF transceivers. Antenna tuners, manual or automatic, seem to be sold as either 9:1 or 32:1 maximum SWR handling, and how much voltage maximum they can handle. I am not the only one with this problem: how do I try new antennas and not destroy my radio amateur equipment? At Yahoo Groups, one QRP radio amateur "popped" his brand new Elecraft automatic antenna tuner that will handle 9:1 SWR. In another thread, here, I asked about a MFJ-939 automatic antenna tuner: If he doesn't operate over 200 watts, what antenna would push the limit of 32:1 SWR? I got one answer so far: avoid multiples of half waves, and feedline length losses control SWR. This answer indicates feedline length can bring an antenna down to a maximim 9:1 or 32:1 SWR but how to determine feedline length for the antenna? I would think it would be better to have an antenna that will not damage or destroy the tuner or the transceiver, then determine the feedline length. Perhaps more to the point: How do I find out the antenna design is over 9:1 SWR limit or the 32:1 SWR limit, to know it will not work for me or bring it down with what feedline length, except to apply low power and then "pop" or "smoke" the not at all cheap automatic antenna tuner or transceiver? The design work is not done for me by others because practically no one mentions SWR maximums in their antenna design writeup or commercial antenna either. I like to try antennas of different designs. How do I try these designs and avoid damaging my QRP and 50 watt maximum transceivers?
