 잠깐 요약을 하면
대충 15만원 정도 가고,무게는 1근 조금 더 나가고, 크기는 주먹 두 개 정도에, 스텐과 알루미늄으로 만들어 졌고, 철사를 15m 정도 묶어서 달아매면 1.9MHz에서 29MHz 까지 S.W.R 1.5 이하로 너끈히 쓸 수 있고, 150W 출력까지 지원된다는 ,한마디로 기가 막히는 발룬 이라는 이야기입니다.

7.메이커 선전문구
  Match All Amateur Automatic Antenna Matcher is a solid-state, non-resonant, broadbanded, constant impedance, induction coupled, traveling wave-type antenna matching device using the latest Maxcom technology adapted to the amateur bands.

  Match All does not depend on resonant lengths of radiating wire or elements to attain proper tuning and radiating results. Also unnecessary are activating RF input signals, control leads or DC voltages to instantly match virtually any antenna configuration on all high frequency amateur bands including WARC and MARS.

  Do not be fooled by an apparent reduction in "S" meter levels when installing a Match All. Being grounded instruments, large amounts of atmospheric noises are eliminated and HF radio becomes a joy to your ears rather than a crackling.

  Match All works best as a dipole or grounded longwire; however, marine, avionics and automotive mobile uses can also be accommodated. Simply call our technical support people at 305-523-3123 for prompt, intelligent information.

  Probably the most important aspect of installing your new Match All is to use a new coax feedline and fully-soldered connectors. The matching instrument must see 50 ohms at the coax input, and dirty, corroded connectors or aged coax will not allow the Match All to work properly. After connecting the feedline to the matcher (without grease or sealants), you must apply the provided Coax-Seal as directed on the envelope. These simple precautions will ensure many years of faultless operation.

  We regret the seemingly small amount of technical information provided to you. The fact is the Match All instrument is inherently simple to install in nearly all antenna installations and, once installed, will never need adjustments, tune-ups or maintenance. In order to provide a high quality instrument at an affordable price, we decided to present only necessary, basic information. At the same time, we remain ready and able to answer questions unique to your particular installation whenever you need it.

  Here's to your increased enjoyment of the wonderful world of HF radio.

8.구입
1994년도 미국에 근무중인 HL2DBT님을 통하여 구입하였으며, 위에 적힌 주소를 통하여 구입이 가능할 것으로 추정됨.

9.설치
  1)다이폴:양쪽 엘레멘트길이를 5m씩 으로 3.5MHz ~ 29MHz 사용
  2)체프형 안테나:아파트 옥상 피뢰침에 한쪽을 접지 시키고, 다른 한쪽은 건너편 아파트 피뢰침에 연결하여 1.8MHz ~ 29MHz band에 사용.(피뢰침 안테나 참조)

10.사용감
수신시 모노밴드 다이폴 또는 적절한 트랩이 들어있는 다이폴 안테나 보다는 좀 떨어지는 성능임.그렇지만 적절한 길이의 다이폴을 칠 수 없는 좁은 지역 이거나, 다양한 다이폴을 칠 수 없는 지역에서는 효과적인 방법이라 생각됩니다.

기능성
  1)모빌운영:Match All을 사용하여 한쪽은 차체에 접지하고 다른 한쪽은 2m용 whip을 사용하면 이동중에도 7MHz 운용이 가능 하리라 생각됨.
  2)Mobil Pedition시 한쪽은 차체에 접지하고 다른 한쪽은 인근 나뭇가지에 묶으면 훌륭한 G.P
  3)이동운영시 Match All을 포함한 한 개의 다이폴로 전밴드 운영..등의 유용성이 크다고 생각 됩니다.
