TEGAM Offers $1000 Credit with HP432 Trade-in Program

Geneva, Ohio -7 September 2011 -TEGAM, Inc. is offering a $1,000 Trade-In Credit for any HP432 Power Meter toward the purchase of a New TEGAM Model 1830A RF Power Meter!

The 1830A (NSN 6625015667703) is a direct reading RF Thermistor Power Meter intended for applications where the lowest uncertainty measurement is important which include metrology, research, and production testing of RF equipment. . It directly replaces the HP432 in most situations and is compatible with all Agilent thermistor power sensors as well and those manufactured by TEGAM. The 1830A also simplifies the measurement task by eliminating the need for external voltmeters and incorporating LXI and USB interfaces.

The guidelines of the trade-in include:

  • Trade-In any number of HP432s toward purchases of like numbers of 1830As!
  • Trade-In units may be working or non-working.
  • Offer Valid through December 31, 2011.

To take advantage of the offer, simply contact TEGAM at 800-666-1010 or with your HP432 serial number(s) to get your quote.

5 October 2011 - Q-par Angus Limited, a microwave antenna and development company based in Leominster, UK, is pleased to announce the launch of a new "base-line" compact ultra-wideband 0.5 -18 GHz spiral antenna intended for UWB communications, feeds, radio surveillance and direction finding applications. The 152 mm diameter antenna is Circularly Polarised (CP) with bore-sight axial ratio better than 3 dB above 0.7 GHz.

After thorough development and testing, this new "base-line" antenna is a welcome addition to Q-par's range of Spiral Antennas. These currently provide wideband performance up to 42 GHz, with either left or right hand CP. The new design will allow Q-par to quickly modify the antenna to meet specific customer requirements, resulting in reduced development lead-times. Spiral antennas are used in many applications because of their low cost and size. They are often used in EW applications such as Radar Warning Receiver (RWR) systems and as Threat Warning Antennas in threat warning receivers.

Robert Lowther, Q-par Angus Sales and Marketing Manager says, "We believe we have developed an excellent ultra wideband spiral antenna that reinforces our position as a leading, innovative microwave antenna company. We are proud to say that this antenna is designed and manufactured in the UK and look forward to launching the antenna at the 2011 European Microwave show in Manchester, UK during October."
