PAR Electronics EF-SWL Antenna

Universal Radio mentions USD 66.95 for the antenna. It is probably worth the price, but it doesn't mean it is better then a home brew construction or give better reception with respect to your current setup. As I said before, a friend of mine has their ham version, which is what I base the following comment on. The quality of construction and materials used is very high. It is not an antenna that your average guy is going to duplicate for a lot less money. Assuming I could figure out the wiring for the loading coil and the traps (his has traps, I don't know if this one does), I could duplicate it, but it would look like something someone with knowledge, but little skill had built (becuase it would be built that way). If I were in the US, I would buy one. Since ordering things like this is difficult, and delivery services cost a small fortune (an order sent via UPS or FEDEX would cost at least $50 and probably $20 in taxes), I would make one an live with what I had. :-) The transformer/common mode choke has same functionality as the PAR antenna. In addition I can disable the 1:9 impedance transformer (while the common mode filter remains). I use a narrow band tunable preselector to avoid "noise" from intermodulation products. Can you describe it better? a 1:9 balun as it were is easy to make, and 1:4 VHF TV/FM radio ones are getting harder to find, but are still out there. Thanks, and 73, Geoff. -- Geoffrey S.
