Abstract: Starting from a complete sample of type I AGN observed by INTEGRAL in the20-40 keV band, we have selected a set of 8 AGN which can be classified asradio loud objects according to their 1.4 GHz power density, radio to hardX-ray flux flux density ratio and radio morphology. The sample contains 6 BroadLine Radio Galaxies and 2 candidate ones. Most of the objects in our sampledisplay a double lobe morphology, both on small and large scales. For all theobjects, we present broad-band 1-110 keV spectral analysis using INTEGRALobservations together with archival XMM-Newton, Chandra, Swift-XRT andSwift-BAT data. We constrain the primary continuum photon index and cut-offenergy, intrinsic absorption and reprocessing features iron line andreflection in most of the objects. The sources analysed here show remarkablesimilarities to radio quiet type 1 AGN with respect to most of the parametersanalysed; we only find marginal evidence for weaker reprocessing features inour objects compared to their radio quiet counterparts. Similarly we do notfind any correlation between the spectral parameters studied and the sourcecore dominance or radio to 20-100 keV flux density ratios, suggesting that whatmakes our objects radio loud has no effect on their high energycharacteristics.
