RoomCap Antenna

If it performs as well as you claim it does, or if it is similar to the performance of an EH per size,(for example, hypothetically speaking, a 3 foot antenna performs as well as a 1/2 wave vertical 20 meter antenna), and if the cost and skill level required for building the antenna is suitable to me, I might be interested in purchasing the plans for your antenna. . . . You must mean, "If it performs as well as the EH antenna claims to perform." If it can do that, it's miraculous indeed. It's no trick to make an antenna perform as well as an EH -- a 3 foot high (fat) vertical performs as well as a 3 foot high EH. Roy Lewallen, W7EL HERE A FEW RESULTS: QRV with RoomCap antenna on 80m On May 15th, 2006 I was QRV on 80 m during 1 1/2 hour. Tcvr: TS-50 (100 W PEP), QRG = 3.770 - 3.787 Mhz Antenna: RoomCap with 1.66m radiator length installed on my car. SWR = 1.0 QTH: Peripheral part of city of Basel. Conditions: The band was weak with a lot of QRN.

Whatever one believes and/or thinks about the EH-Antenna, Ted Hart, the creator and the patent holder, is honest enough to release the full design information to the ham community - to hate or to love. The method of selling sealed envelopes is - at the best regrettable and at worst, something really different. As the EH-Antenna is targeted to the commercial world - this antenna is an obvious way of making money out of the non-commercial hams. I think the judgement are coming down hard on you Felix and I have to agree on this judgement. Again, nothing personal but maybe a very much middle European way of selling. As the Ham world is mainly Anglo-Saxon - it just doesn't work! I suggest you do as the EH-Antenna Inc, release the full info for homebrewers and sell a ready made version to the turn-key amateurs instead! Cheers Dan / M0DFI |
